FamilyTreeDNA Provides Y DNA Haplogroups from Family Finder Autosomal Tests

Big News! FamilyTreeDNA is delivering holiday gifts early!

Y DNA haplogroups are beginning to be delivered as a free benefit to men who took the Family Finder test at FamilyTreeDNA. This is the first wave of a staggered rollout. Haplogroup results will be delivered to several thousand people at a time, in batches, beginning today.

This is no trivial gift and includes LOTS of information that can be used in various ways for your genealogy. Please feel free to share this article. The new Family Finder haplogroups are another reason to take a Family Finder test and to encourage other family members to do so as well.

How is this Even Possible?

Clearly, Y DNA is not autosomal DNA, so how is it possible to obtain a Y DNA or mitochondrial DNA haplogroup from an autosomal test? Great question!

Many autosomal DNA processing chips include a limited number of targeted Y and mitochondrial DNA SNP locations. Generally, those locations are haplogroup predictive, which is how haplogroup information can be obtained from an autosomal DNA test.

Compared to the actual Y DNA and mitochondrial DNA tests, only a small fraction of the information is available through autosomal tests. Only the full sequence mitochondrial DNA test or the Big Y-700 test will provide you with the full story, including your most refined haplogroup, additional information, and matching with other customers.

Having said that, haplogroups obtained from Family Finder provide important clues and genealogical information that will hopefully whet recipients’ appetites for learning even more.

Delivery Schedule

This first group of men to receive haplogroup results consists of testers who have purchased the Family Finder test since March 2019 when the most recent chip was put into production.

FamilyTreeDNA will be rolling haplogroups out in batches of a few thousand each day until everyone’s is complete, in the following order:

  • Family Finder tests purchased since March 2019 (their V3 chip)
  • Family Finder tests purchased between the fall of 2015 to March 2019 (their V2 chip)
  • Family Finder tests purchased from 2010 to the fall of 2015 (their V1 chip)
  • Autosomal uploads from other vendors for customers who have unlocked the advanced Family Finder features for $19

Uploaded DNA Files from Other Vendors

After the results are available for all males who have tested at FamilyTreeDNA, haplogroups will begin to be rolled out to customers who uploaded autosomal DNA files from other companies, meaning MyHeritage, Vitagene, 23andMe, and Ancestry.

To receive haplogroups for files uploaded from other vendors, the Family Finder advanced tool unlock must have been (or can be) purchased for $19. In addition to haplogroups, the unlock also provides access to the chromosome browser, myOrigins (ethnicity), Chromosome painting for myOrigins ethnicity, and ancient Origins.

Both MyHeritage and Vitagene tests are performed in the Gene by Gene lab. Those “uploads” are actually a secure business-to-business transaction, so the file integrity is assured.

Ancestry and 23andMe DNA files are downloaded from those companies, then uploaded to FamilyTreeDNA. Some people build “composite” files in the format of these companies, so FamilyTreeDNA has no way to assure that the original DNA upload file hasn’t been modified and it is a legitimate, unmodified, file from either 23andMe or Ancestry. Hence, in some situations, they are treated differently.

Both Ancestry and 23andMe utilize different chips than FamilyTreeDNA, covering different SNPs. Those results may vary slightly from results available from native FamilyTreeDNA tests, and will also vary from each other. In other words, there’s no consistency, and therefore haplogroup accuracy cannot be confirmed.

Haplogroups resulting from tests performed in the FamilyTreeDNA lab will be visible to matches and on the SNP pages within projects. They will also be used in both Discover and the haplotree statistics. This includes Family Finder plus MyHeritage and Vitagene DNA file uploads.

Tests performed elsewhere will receive haplogroups that will only be visible to the user, or a group administrator viewing a kit within a project. They will not be visible to matches, used in trees or for statistics.

At their recent conference, FamilyTreeDNA provided this slide during an update about what to expect from Family Finder haplogroups.

Today, only Y DNA haplogroups are being provided, but after the new mitochondrial tree is available, customer haplogroups are updated, and MitoDiscover (my name, not theirs) is released, FamilyTreeDNA is planning to provide mitochondrial DNA haplogroups for Family Finder customers as well. The current haplogroup estimate is late 2024 or even into 2025.

Unfortunately, some of Ancestry’s DNA files don’t include mitochondrial DNA SNPs, so some customers who’ve uploaded Ancestry files won’t receive mitochondrial haplogroups.

STR Haplogroups to be Updated

All FamilyTreeDNA customers who have taken Y DNA STR tests, meaning 12, 25, 37, 67, or 111 markers, receive predicted haplogroups. Often, the Family Finder extracted results can provide a more refined haplogroup.

When that is possible, STR test predicted haplogroup results will be updated to the more refined Family Finder haplogroup.

Furthermore, while STR results are quite reliably predicted, Family Finder results are SNP-confirmed.

Notification

When your Family Finder test has received a haplogroup or your STR-derived haplogroup has been updated, you’ll receive an email notification with a link to a short, less than 2-minute video explaining what you’re receiving.

You can also expect emails in the following days with links to additional short videos. If you’d like to watch the videos now, click here.

You can also check your results, of course. If you should have received an email and didn’t, check your spam folder, and if it’s not there, notify FamilyTreeDNA in case your email has managed to get on the bounce list.

Group project administrators will receive notifications when a haplogroup is updated for a member in a project that they manage. This doesn’t just apply to Family Finder haplogroup updates for STR results – notifications will arrive when Big Y haplogroups are updated, too.

Emails about haplogroup updates will include both the old and the updated haplogroup.

Haplogroups may change as other testers receive results, forming a new haplogroup. The Big Y-700 test is evergreen, meaning as the Y tree grows, testers’ results are updated on an ongoing basis.

New View

Let’s take a look at what customers will receive.

In one of my surname projects, one male has taken a Family Finder test, but not the Y DNA test.

Several other men in that same paternal line, who are clearly related (including his brother), have taken Y DNA tests – both STR and the Big Y-700.

We have men who have taken the Big Y-700 test, STR tests only (no Big Y), and one with only a Family Finder test, so let’s compare all three, beginning with the man who has taken a Family Finder test but no Y DNA tests.

He has now been assigned to haplogroup I-BY1031, thanks to his Family Finder test.

Before today, because he has not taken a Y DNA test, he had no haplogroup or Y DNA Results section on his personal page.

Today, he does. Of course, he doesn’t have STR results or matches, but he DOES have confirmed SNP results, at least part way down the tree.

He can view these results on the Haplotree & SNPs tab or in Discover. Let’s look at both.

Haplotree & SNPs

By clicking on the Haplotree & SNPs link, you can view the results by variants (mutations,) as shown below, or by countries, surnames, or recommended projects for each haplogroup.

Of course, as more Family Finder results are rolled out, the more names and countries will appear on the Haplotree.

Recommended Projects

It’s easy to determine which haplogroup projects would be a good fit for people with these new haplogroups to join.

Just view by Recommended Projects, then scan up that column above the selected haplogroup. You can even just click right there to join. It’s that easy!

Results still won’t show on the public project page, because these testers don’t have STR results to display. Perhaps this will encourage additional testing in order to match with other men.

Download SNP Results

If you’re interested, you can download your SNP results in spreadsheet format.

I’m only showing four of my cousin’s positive SNPs, but FamilyTreeDNA was able to extract 358 positive SNPs to assign him to haplogroup I-BY1031.

Are Family Finder Haplogroups Better Than STR Test Predicted Haplogroups?

How do Family Finder haplogroups stack up against STR-predicted haplogroups?

Viewing the Y DNA results of related cousins who have taken STR tests, but not the Big Y-700, we see that their Y DNA haplogroup was predicted as I-M253.

We also know that the haplogroup determined by the Big Y-700 for this line is I-BY73911.

How can we use this information beneficially, and what does it mean?

Discover

Family Finder haplogroups can access Discover, which I wrote about, here.

Clicking on the Discover link takes you to your haplogroup story.

Let’s look at the new Family Finder Haplogroup Story for this tester.

Haplogroup I-BY1031 is about 3100 years old and is found in England, Sweden, the US, and 14 other countries. Of course, as more Family Finder haplogroups are provided to customers, this information will change for many haplogroups, so check back often.

Of course, you’ll want to review every single tab, which are chapters in your ancestral story! The Time Tree shows your haplogroup age in perspective to other haplogroups and their formation, and Ancient Connections anchors haplogroups through archaeology.

You can share any Discover page in several ways. This is a good opportunity to excite other family members about the discoveries revealed through DNA testing and genealogy. Prices are reduced right now with the Holiday Sale, too, so it’s a great time to gift someone else or yourself.

Compare – How Good is Good?

Ok, so how much better is the Family Finder haplogroup than the STR-predicted haplogroup, and how much better is the Big Y-700 haplogroup than the other two?

I’ll use the Discover “Compare” feature to answer these questions.

First, let’s compare the STR-predicted haplogroup of I-M253 to the Family Finder haplogroup of I-BY1031.

I clicked on Compare and entered the haplogroup I wish to compare to I-BY1031.

I-M253 I-BY1031 I-BY73199
Haplogroup Source STR Predicted Family Finder Big Y-700
Formation Year 2600 BCE 1100 BCE 1750 CE
Age – Years ago 4600 3100 270
Era Stone Age, Metal Age Metal Age Modern
Ancestral Locations England, Sweden, Germany, UK, +100 Sweden, England, US, +14 Netherlands
Tested Descendants 26,572 121 2
Branches 6779 69 0 – this is the pot-of-gold end leaf on the branch today

I created this chart to compare the major features of all three haplogroups.

The STR-predicted haplogroup, I-M253, takes you to about 2,600 BCE, or about 4,600 years ago. The Family Finder haplogroup shifts that significantly to about 1100 BCE, or 3100 years ago, so it’s about 1500 years more recent. However, the Big Y haplogroup takes you home – from 3100 years ago to about 270 years ago.

Notice that there’s a LOT of room for refinement under haplogroup I-M253. A Big Y tester might wind up on any of those 6779 branches, and might well be assigned to a newly formed branch with his test. The Family Finder haplogroup, I-BY1031, which was, by the way, discovered through Big Y testing, moved the autosomal test taker forward 1500 years where there are 121 descendants in 69 branches. The Big Y-700 test is the most refined possible, moving you directly into a genealogically relevant timeframe with a very specific location.

I-M253 is found in over 100 countries, I-BY1031 in 17 and I-BY73199 is found only in one – the Netherlands.

Based on confirmed genealogy, the common ancestor of the two men who have Big Y-700 haplogroup I-BY73199 was a man named Hendrik Jans Ferwerda, born in 1806 in the Netherlands, so 217 years ago. Of course, that haplogroup itself could have been born a generation or two before Hendrik. We simply won’t know for sure until more men test. More testers refine the haplotree, haplogroup ages, and refine our genealogy as well.

Haplogroup Comparison and Analysis

Let’s look at the Discover “Compare” feature of the three haplogroups from my family line from the Netherlands. Please note that your results will differ because every haplogroup is different, but this is a good way to compare the three types of haplogroup results and an excellent avenue to illustrate why testing and upgrades are so important.

The haplogroup ages are according to the Discover Time Tree.

FT230048
BY65928
BY61100
I-BY73199 lived about 270 years ago

 All of the base haplogroups in the first column leading to Haplogroup I span the longest elapsed time, about 230,000 years, from Y-Adam to I-M253, the STR-predicted haplogroup, but are the least relevant to contemporary genealogy. They do tell us where we came from more distantly.

The second column moves you about 1500 years forward in time to the Family Finder confirmed haplogroup, reducing the location from pretty much everyplace in Europe (plus a few more locations) with more than 6700 branches, to 69 branches in only 17 countries.

With the fewest haplogroups, the third column spans the most recent 2800 years, bringing you unquestionably into the genealogically relevant timeframe, 270 years ago, in only one country where surnames apply.

If we had more testers from the Netherlands or nearby regions, there would probably be more branches on the tree between BY1031 and BY73199, the Big Y-700 haplogroup.

The second column is clearly an improvement over the first column which gets us to I-M253. The Family Finder upgrade from I-M253 to BY1031 provides information about our ancestors 3000-4500 years ago, where they lived and culturally, what they were doing. Ancient Connections enhance that understanding.

But the third column moves into the modern area where surnames are relevant and is the holy grail of genealogy. It’s a journey to get from Adam to the Netherlands in one family 270 years ago, but we can do it successfully between Family Finder and the Big Y-700.

Family Finder Matching

Given that these new haplogroups result from Family Finder, how do these results show in Family Finder matching? How do we know if someone with a haplogroup has taken a Y DNA test or if their haplogroup is from their Family Finder test?

  • All Family Finder haplogroups will show in the results for people who tested at FamilyTreeDNA as soon as they are all rolled out
  • All MyHeritage and Vitagene uploads, because they are processed by the Gene by Gene lab, will be shown IF they have purchased the unlock.
  • No Ancestry or 23andMe haplogroups will be shown to Family Finder matches

To determine whether or not your matches’ haplogroups result from a Y DNA test or a Family Finder haplogroup, on your Family Finder match page, look just beneath the name of your matches.

The first man above received the Family Finder haplogroup. You can see he has no other tests listed. The second man has taken the Big Y-700 test. You can see that he has a different haplogroup, and if you look beneath his name, you’ll see that he took the Big Y-700 test.

For other men, you may see the 67 or 111 marker tests, for example, so you’ll know that they are available for Y-DNA matching. That may be important information because you can then visit the appropriate surname project to see if they happen to be listed with an earliest known ancestor.

After the rollout is complete, If you have a male Family Finder match with no haplogroup shown, you know that:

  • They did not test at FamilyTree DNA
  • If they uploaded from MyHeritage or Vitagene, they did not unlock the advanced Family Finder features
  • Or, they tested at either 23andMe or Ancestry, and uploaded their results

You can always reach out to your match and ask.

How to Use This Information

There are several great ways to utilize this new information.

I have a roadblock with my Moore line. Moore is a common surname with many, many origins, so I have autosomal matches to several Moore individuals who may or may not be from my Moore line.

I do know the base haplogroup of my Moore men, but I do not have a Big Y, unfortunately, and can’t upgrade because the tester is deceased. (I wish I had ordered the Big Y out the gate, but too late now.)

As soon as the results are complete for all of the testers, I’ll be able, by process of elimination to some extent, focus ONLY on the testers who fall into Family Finder haplogroup of my Moore cousins, or at least haplogroup close for Ancestry or 23andMe upload customers. In other words, I can eliminate the rest.

I can then ask the men with a similar haplogroup to my proven Moore cousins for more information, including whether they would be willing to take a Y DNA test.

  • Second, as soon as the Family Finder processing is complete, I will know that all male Family Finder matches and uploads from MyHeritage and Vitagene that have paid for the unlock will have haplogroups displayed on the Family Finder Match page. Therefore, if there’s a male Moore with no haplogroup, I can reach out to see where they tested and if a haplogroup has been assigned, even if it’s from Ancestry or 23andMe and isn’t displayed in Family Finder.

If so, and they share the haplogroup with me, I’ll be able to include or exclude them. If included, I can then ask if they would consider taking a Y DNA test.

  • Third, for lines I don’t yet have Y DNA testers for, I can now peruse my matches, and my cousins’ matches for that line. See items one and two, above. Even if they don’t reply or agree to Y DNA testing, at least now I have SOME haplogroup for that missing line.

Discover will help me flesh out the information I have, narrow regions, find projects, look at ancient DNA for hints, and more.

  • Fourth, the haplogroups themselves. I don’t know how many million tests FamilyTreeDNA has in their database, but if we assume that half of those are male, some percentage won’t have taken a Y DNA test at all. We’ll be able to obtain Y-DNA information for lines where there may be no other living descendant. I have at least one like that. He was the end of the surname line and is deceased, with no sons.

I’m literally ecstatic that I’ll be able to obtain at least something for that line. If it’s anything like my example Netherlands lineage, the Family Finder haplogroup may be able to point me to an important region of Europe – or maybe someplace else very unexpected.

The Bottom Line

Here’s the bottom line. You don’t know what you don’t know – and our ancestors are FULL of surprises.

I can’t even begin to tell you how MUCH I’m looking forward to this haplogroup rollout.

To prepare, I’m making a list of my genealogical lines:

  • If the paternal line, meaning surname line, is represented by any match in any database
  • If that line is represented by a known person in the FamilyTreeDNA database and by whom
  • If they or someone from that line has joined a surname or other FamilyTreeDNA project, and if so, which one
  • If they’ve taken a Y DNA test, and what kind – watch STR results for an updated haplogroup
  • If they’ve taken a Family Finder test – my cousin is a good example of a known individual whose kit I can watch for a new haplogroup
  • Old and new haplogroup, if applicable

If my only relative from that line is in another vendor’s database, I’ll ask if they will upload their file to FamilyTreeDNA – and explain why by sharing this article. (Feel free to do the same.) A Y DNA haplogroup is a good incentive, and I would be glad to pay for the unlock at FamilyTreeDNA for cousins who represent Y and mitochondrial DNA lines I don’t already have.

One way I sweeten the pie is to offer testing scholarships to select lines where I need either the Y DNA or mitochondrial DNA of relevant ancestors. It’s a good thing these haplogroups are being rolled out a few thousand at a time! I need to budget for all the scholarships I’ll want to offer.

I feel like I won the lottery, and FamilyTreeDNA is giving me a free haplogroup encyclopedia of information about my ancestors through my cousins – even those who haven’t taken Y DNA tests. I can’t even express how happy this makes me.

What lines do you want to discover more about, and what is your plan? Tests are on sale now if you need them!

Y-DNA Haplogroup O – When and How Did It Get to the Americas?

Y-DNA Haplogroup O has been found in male testers descended from a Native American ancestor, or in Native American tribes in the Americas – but sometimes things are more complex than they seem. The story of when and how haplogroup O arrived in the Americas is fascinating – and not at all what you might think.

Introduction

The concept of Native American heritage and indigenous people can be confusing. For example, European Y-DNA haplogroup R is found among some Native American men. Those men may be tribal members based on their mother’s line, or their haplogroup R European Y-DNA may have been introduced either through adoption practices or traders after the arrival of Europeans.

There is unquestionable genetic evidence that the origin of Haplogroup R in the Americas was through colonization, with no evidence of pre-contact indigenous origins.

Y-DNA testing and matching, specifically the Big Y-700 test, with its ability to date the formation of haplogroups very granularly, has successfully identified the genesis of Y-DNA haplogroups and their movement through time.

We’ve spent years trying to unravel several instances of Native American Y-DNA Haplogroup O and their origins. Native American, in this context, means that men with haplogroup O are confirmed to be Native American at some point in documented records. This could include early records, such as court or probate records, or present-day members of tribes. There is no question that these men are recognized as Native American in post-contact records or are tribal members, or their descendants.

What has not been clear is how and when haplogroup O entered the Native American population of these various lineages, groups, or tribes. In other words, are they indigenous? Were they here from the earliest times, before the arrival of colonists, similar to Y-DNA haplogroups C and Q?

This topic has been of great interest for several years, and we have been waiting for additional information to elucidate the matter, which could manifest in several ways:

  1. Ancient pre-contact DNA samples of haplogroup O in the Americas, but none have been found.
  2. Current haplogroup O testers in Native American peoples across the North and South American continents, forming a connecting trail genetically, geographically, and linearly through time. This has not occurred.
  3. Big-Y DNA matches within the Americas between Haplogroup O Native American lines unrelated in a genealogical timeframe whose haplogroup formation pre-dates European contact. This has not occurred.
  4. Big-Y DNA matches between Haplogroup O men whose haplogroups were formed in the Americas after the Beringian migration and expansion that scientists agree occurred at least 12-16K years ago, and possibly began earlier. Earlier human lineages, if they existed, may not have survived. A later Inuit and Na-Dené speaker circumpolar migration occurred 4-7K years ago. This has not occurred.
  5. Big-Y DNA matches with men whose most recent common ancestor haplogroup formation dates connect them with continental populations in other locations, outside of North and South America. This would preclude their presence in the Americas after the migrations that populated the Americas. This has occurred.

The Beringian migration took place across a now-submerged land bridge connecting the Chutkin Peninsula in Russia across the Bering Strait with the Seward Peninsula in Alaska.

By Erika Tamm et al – Tamm E, Kivisild T, Reidla M, Metspalu M, Smith DG, et al. (2007) Beringian Standstill and Spread of Native American Founders. PLoS ONE 2(9): e829. doi:10.1371/journal.pone.0000829. Also available from PubMed Central., CC BY 2.5, https://commons.wikimedia.org/w/index.php?curid=16975303

Haplogroup O is clearly Native American in some instances, meaning that it occurs in men who are members of or descend from specific Native American tribes or peoples. One man, James Revels, is confirmed in court records as early as 1656. However, ancestors of James Revels fall into category #5, as their upstream parental haplogroup is found in the Pacific islands outside the Americas after the migration period.

Based on available evidence, the introduction of haplogroup O appears to be post-contact. Therefore, haplogroup O is not indigenous to the Americans in the same sense as haplogroups Q and C that are found widespread throughout the Americas in current testers who are tribal members, descendants of tribal members, and pre-contact ancient DNA as mapped in the book, DNA for Native American Genealogy.

Ancient DNA

Haplogroup C is found in both North and South America today, as are these ancient DNA locations.

Haplogroup Q is more prevalent than Haplogroup C, and ancient DNA remains are found throughout North and South America before colonization.

No ancient DNA for Haplogroup O has been discovered in the Americas. We do find contemporary haplogroup O testers in regional clusters, which we will analyze individually.

Let’s take a look at what we have learned recently.

Wesley Revels’ Lineage

Wesley Revels was the initial Y-DNA tester whose results identified Haplogroup O as Native American, proven by a court record. That documentation was critical, and we are very grateful to Wesley for sharing both his information and results.

Wesley’s ancestor, James Revels, was Native American, born about 1656 and bound to European planter, Edward Revell. James was proven in court to be an Accomack “Indian boy” from “Matomkin,” age 11 in 1667. James was bound, not enslaved, until age 24, at which time he was to be freed and receive corn and clothes.

James had died by 1681 when he was named several times in the Accomack County records as both “James, an Indian” and “James Revell, Indian,” in reference to his estate. James lived near Edward Revell, his greatest creditor and, therefore, administrator of his estate, and interacted with other Indian people near Great Matompkin Neck. Marie Rundquist did an excellent job of documenting that here. Additional information about the Revels family and Matomkin region can be found here.

The location where Edward Revell lived, Manokin Hundred, was on the water directly adjacent the Great Matomkin (now Folly Creek) and Little Matomkin Creeks, inside the Metomkin Inlet. The very early date tells us that James Revels’s paternal ancestor was in the colonies by 1656 and probably born about 1636, or perhaps earlier.

Lewis and Revels men are later associated with the Lumbee Tribe, now found in Robeson and neighboring counties in North Carolina. The Lewis line descends from the Revels lineage, as documented by Marie and Wesley. Other men from this line have tested and match on lower-level STR markers, but have not taken the much more granular and informative Big-Y test.

Until recently, the men who matched Wesley Revels closely on the Big-Y test were connected with the Revels line and/or the Lumbee.

Wesley has a 37-marker STR match to a man with a different surname who had not tested beyond that level, in addition to several 12-marker STR matches to men from various locations. Men who provided known ancestral or current locations include one from Bahrain, two from the Philippines, and three from China. Those men have not taken the Big-Y, and their haplogroups are all predicted from STR results to O-M175 which was formed in Asia about 31,000 years ago.

12-marker matches can reach thousands of years back in time. Unless the matches share ancestors and match at higher levels, 12-marker matches are only useful for geographic history, if that. The Big Y-700 test refines haplogroup results and ages from 10s of thousands of years to (generally) within a genealogically relevant timeframe, often within a couple hundred years.

One of Wesley’s STR matches, Mr. Luo, has taken a Big Y-700 test. Mr. Luo descends directly from Indonesia in the current generation and is haplogroup O-CTS716, originating about 244 BCE, or 2244-ish years ago. Mr. Luo does not match Wesley on the Big-Y test, meaning that Wesley and Mr. Luo have 30 or more SNP differences in their Big-Y results, which equates to about 1,500 years. The common ancestor of Wesley Revels and Mr. Luo existed more than 1,500 years ago in Indonesia. It’s evident that Mr. Luo is not Native American, but his location is relevant in a broader analysis.

There is no question that Wesley’s ancestor, James Revels, was Native American based on the court evidence. There is also no question that the Revels’ paternal lineage was not in the Americas with the Native American migration group 12-16K years ago.

The remaining question is how and when James Revels’ haplogroup O ancestor came to be found on the Atlantic seaboard in the early/mid 1600s, only a few years after the founding of Jamestown.

The results of other Haplogroup O men may help answer this question.

Mr. Lynn

Another haplogroup O man, Mr. Lynn, matches Wesley on STR markers, but not on the Big-Y test.

Mr. Lynn identified his Y-DNA line as Native American, although he did not post detailed genealogy. More specifically, we don’t know if Mr. Lynn identified that he was Native on his paternal line because he matches Wesley, or if the Native history information was passed down within his family, or from genealogical research. Mr. Lynn could also have meant generally that he was Native, or that he was Native “on Dad’s side,” not specifically his direct patrilineal Y-line.

Based on Mr. Lynn’s stated Earliest Known Ancestor (EKA) and additional genealogical research performed, his ancestor was John Wesley Lynn (born approximately 1861, died 1945), whose father was Victor Lynn. John’s death certificate, census, and his family photos on Ancestry indicate that he was African American. According to his death certificate, his father, Victor Lynn, was born in Chatham Co., NC, just west of Durham.

Family members are found in Baldwin Township, shown above.

I did not locate the family in either the 1860 or 1870 census. In 1860, the only Lynn/Linn family in Chatham County was 50-year-old Mary Linn and 17-year-old Jane, living with her, presumably a daughter. Both are listed as “mulatto” (historical term) with the occupation of “domestic.” They may or may not be related to John Wesley Lynn.

In 1870, the only Linn/Lynn in Chatham County is John, black, age 12 or 13 (so born in 1857 or 1858), farm labor, living with a white family. This is probably not John Wesley Lynn given that he is found with his mother in 1880 and the ages don’t match.

In 1880. I find Mary Lynn in Chatham County, age 48, single, black, with daughter Eliza Anne, 20, mulatto, sons John Wesley, 14 so born about 1866, and Charles 12, both black. Additionally, she is living with her nieces and nephews, Cephus, black, 12, Lizzie, 7, mulatto, Malcom, 4, mulatto, William H, 3, mulatto (I think, written over,) and John age 4, mulatto. The children aged 12 and above are farm labor.

In 1880, I also find Jack Lynn, age 28, black, married with 3 children, living beside William Lynn, 25, also married, but with no children.

Trying to find the family in 1870 by using first name searches only, I find no black Mary in 1870 or a mulatto Mary with a child named Jack or any person named Cephus by any surname. I don’t find Jack or any Lynn/Linn family in Chatham County.

The 1890 census does not exist.

In the 1900 census, I find Wesley Lynn in Chatham County, born in January of 1863, age 37, single, a boarder working on the farm of John Harris who lives beside Jack Lynn, age 43, born in April of 1857. Both Lynn men are black. I would assume some connection, given their ages, possibly or probably brothers.

In 1940, John Wesley Lynn, age 74, negro (historical term), is living beside Victor Lynn, age 37, most likely his son.

I could not find Victor Lynn, John Wesley Lynn’s father in any census, so he was likely deceased before 1880 but after 1867, given that Mary’s son Charles Lynn was born in 1868, assuming Mary’s children had the same father. The fact that Mary was listed as single, not married nor widowed suggests enslavement, given that enslaved people were prohibited from legally marrying.

About the only other assumption we can make about Victor Sr. is that he was probably born about 1832 or earlier, probably in Chatham County, NC based on John Wesley’s death certificate, and he was likely enslaved.

Subclades of Haplogroup O

Both the Revels and Lynn men are subclades of haplogroup O and both claim Native heritage – Wesley based on the Revels genealogy and court documents, and Mr. Lynn based on the Native category he selected to represent his earliest known paternal ancestor at FamilyTreeDNA.

Both men have joined various projects, including the American Indian Project, which provides Marie and me, along with our other project co-administrators, the ability to work with and view both of their results at the level they have selected.

How Closely Related Are These Haplogroup O Men?

How closely related are these two men?

  • Do the haplogroups of the Revels men and Mr. Lynn converge in a common ancestor in a timeframe BEFORE colonialization, meaning before Columbus “discovered” the Caribbean islands when colonization and the slave trade both began?
  • Do the haplogroups converge on North or South American soil or elsewhere?
  • Is there anything in the haplogroup and Time Tree information that precludes haplogroup O from being Native prior to the era of colonization?
  • Is there anything that confirms that a haplogroup O male or males were among the groups of indigenous people that settled the Americas sometime between 12 and 26 thousand years ago? Or even a later panArctic or circumpolar migration wave?

Haplogroup O is well known in East Asia, Indonesia, and the South Pacific.

Another potential source of haplogroup O is via Madagascar and the slave trade.

The Malagasy Roots Project has several haplogroup O individuals, including the Lynn and Revels men, who may have joined to see if they have matches. We don’t know why the various haplogroup O men in the project joined. Other haplogroup O men in the project may or may not have proven Malagasay heritage.

Information provided by the project administrators is as follows:

The people of Madagascar have a fascinating history embedded in their DNA. 17 known slave ships came from Madagascar to North America during the Transatlantic Slave Trade. As a result, we find Malagasy DNA in the African American descendants of enslaved people, often of Southeast Asian origin. One of the goals of this project is to discover the Malagasy roots of African Americans and connect them with their cousins from Madagascar. Please join us in this fascinating endeavor. mtDNA Haplogroups of interest include: B4a1a1b – the “Malagasy Motif”, M23, M7c3c, F3b1, R9 and others Y-DNA Haplogroups include: O1a2 – M50, O2a1 – M95/M88, O3a2c – P164 and others

The Malagasy group only has one other man who is haplogroup O and took the Big-Y test, producing haplogroup O-FTC77008. Of course, we don’t know if he has confirmed Madagascar ancestry, and his haplogroup is quite distant from both Revels and Lynn in terms of when his haplogroup was formed.

Viewing the Malagasy Project’s Group Time Tree, above, the common ancestor between those three men lived about 28K BCE, or 30,000 years ago.

Haplogroup O Project Group Time Tree

The Haplogroup O Project Time Tree provides a better representation of haplogroup O in general given that it has a much wider range of samples.

On this tree, I’ve labeled the haplogroup formation dates, along with the Revels/Lewis line which descends from O-FT45548. This haplogroup includes one additional group member whose surname is locked, as he hasn’t given publication permission. The haplogroup formation date of 1766 occurs approximately 85 years after James Revel’s birth, so is attributable to some, but not all of his descendants. At least one descendant falls into the older Haplogroup O-BY60500.

The common ancestor of all three, meaning Revels, Lewis, and the man whose name is locked and does not know his genealogy, is haplogroup O-BY60500, born about 1741.

Their ancestral haplogroup before that, O-FT11768, is much older.

Two Filipino results are shown on and descending from the parent branch of O-FT11768, formed about 3183 BCE, or about 5183 years ago. This tells us that the ancestors of all these men were in the same place, most likely the Philippines, at that time.

3183 BCE (5180 years ago) is well after the Native American migration into the Americas.

Discover Time Tree

Obviously, not every tester joins a project, so now I’m switching to the Discover Time Tree which includes all Y-DNA haplogroup branches. Their common haplogroup, O-FT11768, has many branches, not all of which are shown below. I’m summarized unseen branch locations at bottom left.

Expanding the Time Tree further to view all of the descendant haplogroups of O-FT11768, we see that this was a major branch with many South Pacific results, including the branch of O-FT22410, bracketed in red, which has three members.

One is Mr. Lynn whose feather indicates Native American as his EKA country selection, one is a man whose ancestor is from Singapore, and one is an unknown individual who did not enter his ancestor’s country of origin.

Geography

Wesley’s STR match list, which can reflect matches further back in time than the Big-Y test, includes islands near Singapore. This geography aligns with what is known about haplogroup O.

The distance between this Asian region and continental America, 9000+ miles distant by air, is remarkable and clearly only navigable at that time by ship, meaning ships with experienced crew, able to navigate long distances with supplies and water.

We know that in 760 CE, about 1240 years ago, Mr. Lynn’s haplogroup O-F24410 was formed someplace in the South Pacific – probably in Malaysia or a nearby island. This region, including the Philippines, is home to many haplogroup O men. The majority of haplogroup O is found in Asia, the South Pacific, and Diaspora regions.

We know that Hawaii was populated by Polynesian people about 1600 years ago, prior to the age of colonization. Hawaii is almost 7000 miles from Singapore.

Here’s the challenge. How did these haplogroup O men get from the South Pacific to Virginia? Mr. Lynn and the Singapore tester share a common ancestor about 1240 years ago, or 760 CE.

There is no known or theorized Native American settlement wave across Beringia as late as 760 CE. We know that the parent haplogroup was someplace near Singapore in approximately 760 CE.

Two Filipino men and the Revels’ ancestors were in the same location in the Pacific Islands 5180 years ago. How did they arrive on the Eastern Shore in Virginia, found in the Native population, either in or before 1656 when James Revels was born?

What happened in the 3500 years between those dates that might explain how James Revel’s ancestor made that journey?

Academic Papers

In recent years, there has been discussion of possible shoreline migration routes along the Russian coast, Island hopping along Alaska, Canada, and what is now the US, known as the Kelp Highway or Coastal Migration Route – but that has yet to be proven.

Even if that is the case, and it’s certainly a possibility, how did this particular group of men get from the Pacific across the continent to the Atlantic shore in such a short time, leaving no telltale signs along the way? The Coastal Migration Theory hypothesis states that this migration occurred from 12-16 thousand years ago, and then expanded inland over the next 3-5K years. They could not have expanded eastward until the glaciers receded. Regardless, the parent haplogroup and associated ancestors are still found in the Philippines and South Pacific 5000 years ago – after that migration and expansion had already occurred.

The conclusion of the paper is that there is no strong evidence for a Pacific shoreline migration. Regardless, that’s still thousands of years before the time range we’re observing.

We know that the Lynn ancestor was with men from Indonesia in 760 CE, and the Revels ancestor was with men from the Pacific Islands, probably the Philippines, 5180 years ago. They couldn’t have been in two places at the same time, so the ancestors of Revels and Lynn were not in the Americas then.

A 2020 paper shows that remains from Easter Island (Rapa Nui) show Native American DNA, and suggests that initial contact occurred between the two cultures about 1200 CE, or about 800 years ago, but there is not yet any pre-contact or post-contact ancient Y-DNA found in the Americas that shows Polynesian DNA. Furthermore, the hypothesis is that the DNA found on Easter Island came from the Americas, not vice versa. The jury is still out, but this does show that trans-Pacific contact between the two cultures was taking place 800 years ago, at least two hundred years pre-European contact.

Australasian migration to South America is also suggested by one set of remains found in Brazil dating from more than 9000 years ago, but there have been no other remains found indicating this heritage, either in Brazil, or elsewhere in the Americas.

Based on the Time Tree dates of the Haplogroup O testers in our samples, we know they were in the Islands of Southeast Asia after this time period. Additionally, there are no Australia/New Zealand matches.

The Spanish

The Spanish established an early trade route between Manila and Acapulco beginning in 1565. Consequently, east Asian men left their genetic signature in Mexico, as described in this paper.

Historians estimate that 40-129K immigrants arrived from Manilla to colonial Mexico between 1565 and 1815, with most being enslaved upon arrival. Approximately one-third of the population in Manilla was already enslaved. Unfortunately, this paper focused only on autosomal genome-wide results and did not include either Y-DNA, nor mitochondrial. However, the paper quantifies the high degree of trade, and indicates that the Philippines and other Asian population haplotypes are still prevalent in the Mexican population.

In 2016, Dr. Miguel Vilar, the lead scientist with the National Geographic Genographic project lectured in Guam about the surprising Native American DNA found in the Guam population and nearby islands. He kindly provided this link to an article about the event.

Guam was colonized by Spain. In the image from the Boxer Codex, above, the local Chamorro people greet the Manila Galleon in the Ladrones Islands, as the Marianas were called by the Spanish, about 1590.

Native Hawaiians descend from Polynesian ancestors who arrived in the islands about 400 CE, or about 1600 years ago. Captain Cook, began the age of European contact in Hawaii in 1778.

Five Possibilities

There are five possible origins of haplogroup O in the Americas.

  • Traditional migration across Beringia with the known migrations, estimated to have occurred about 12-16K years ago.
  • A Kelp Highway Coastal Migration which may have occurred about 12-16K years ago and dispersed over the next 3-5K years.
  • Circumpolar migration – specifically Inuit and Na-Dene speakers, about 4-6K years ago.
  • Post-contact incorporation from the Pacific Islands resulting from shipping trade on colonial era ships sometime after 1565.
  • Post-contact incorporation from Madagascar resulting from the importation of humans who may or may not have been enslaved upon arrival.

Do we have any additional evidence?

Other Haplogroup O DNA

From my book, DNA for Native American Genealogy:

Testers in haplogroup O-BY60500 and subclade O-FT45548 have proven Native American heritage.

We have multiple confirmed men from a common ancestor who is proven to be an enslaved Accomack “Indian boy,” James Revell, born in 1656, “belonging to the Motomkin” village, according to the Accomack County, Virginia court records. These men tested as members of haplogroup O-F3288 initially, after taking the Big Y-500 test. However, upgrading to the Big Y-700 produced more granular results and branches reflecting mutations that occurred since their progenitor was born in 1656.

Unfortunately, other than known descendants, these men have few close Y-DNA or Big Y-700 matches.

Without additional men testing from different unrelated lines, or ancient haplogroup O being discovered, we cannot confirm that this haplogroup O male’s ancestor was not introduced into the Matomkin Tribe in some way post-contact. Today, one descendant from this line is a member of the Lumbee Tribe.

However, that isn’t the end of the haplogroup O story.

The Genographic Project data shows one Haplogroup O Tlingit tribal member from Taku, Alaska, along with several testers from Mexico that indicate their paternal line is indigenous. Some people from Texas identify their paternal line as Hispanic.

Another individual indicates they were born on the Fountain Indian Reserve, in British Columbia and speaks the St’at’imcets language, an interior branch of Coastal Salish.

Haplogroup O has been identified as Native American in other locations as well.

Much of the information about Haplogroup O testers was courtesy of the Genographic Project, meaning we can’t contact those people to request upgraded tests, and we can’t obtain additional information in addition to what they provided when they tested. As an affiliate researcher, I’m very grateful to the National Geographic Society’s Genographic project for providing collaborative data.

When the book was published, the Discover Time Tree had not yet been released. We have additional information available today, including the dates of haplogroup formation.

FamilyTreeDNA Haplotree and Discover

The FamilyTreeDNA Haplotree (not to be confused with the Discover Time Tree) shows 10 people at the O-M175 level in Mexico, 10 people in the US report Native American heritage, 2 in Jamaica, and one each in Peru, Panama, and Cuba. There’s also one tester from Madagascar.

Altogether, this gives us about 35 haplogroup O males in the Americas, several with Native heritage.

Please note that I’ve omitted Hawaii in this analysis and included only North and South America. The one individual selecting Native Hawaiian (Kanaka Maoli) is in haplogroup O-M133.

Let’s look at our three distinct clusters.

Cluster 1 – Pacific Northwest – Alaska and Canada

We have a cluster of three individuals along the Pacific Coast in Alaska and Canada who have self-identified as Native, provided a tribal affiliation, and, in some cases, the spoken language.

How might haplogroup O have arrived in or near Vancouver, Washington? We know that James Cook “discovered” Hawaii in 1778, naming it the Sandwich Islands. By 1787, a female Hawaiian died en route to the Pacific Northwest, and the following year, a male arrived. Hawaii had become a provisioning stop, and the Spanish took Hawaiians onto ships as replacement workers.

Hawaiian seamen, whalers, and laborers began intermarrying with the Native people along the West Coast as early as 1811. Their presence expanded from Oregon to Alaska. Migration and intermarriage along the Pacific coast began slowly, but turned into a steady stream 30 years later when we have confirmed recruitment and migration of Hawaiian people

In 1839, John Sutter recruited a small group of 10 Hawaiians to travel with him to the then-Mexican colony of Alta, California.

By the mid-1800s, hundreds of Hawaiians lived in Canada and California. In 1847, it was reported that 10% of San Francisco’s residents were Hawaiian. Some of those people integrated with the Native American people, particularly the Miwok and Maidu. The village of Verona, California was tri-lingual: Hawaiian, a Native language, and English, and is today the Sacramento-Verona Tribe.

This article provides a history of the British Company who administered Fort Vancouver, near Vancouver, Washington, that included French-Canadians, Native Americans and Hawaiians. In 1845, 119 Hawaiians were employed at the fort. One of the 119, Opunuia, had signed on as an “engagé,” meaning some type of hired hand or employee, with the Hudson Bay Company for three years, after which he would be free to return home to Honolulu or establish himself in the Oregon Country. He married a woman from the Cascade Tribe.

The descendants of the Hawaiian men and Native women were considered tribal members. In most tribes, children took the tribal status and affiliation of the mother.

The Taku and Sitka, Alaska men on the map are Tlingit, and the man from British Columbia is from the Fountain Indian Reserve.

Hawaiian recruitment is the most likely scenario by which haplogroup O arrived in the tribes of the Pacific Northwest. In that sense, haplogroup O is indeed Native American but not indigenous to that region. The origins of haplogorup O in the Pacific Northwest are likely found in Hawaii, where it is indigenous, and before that, Polynesia – not due to a Beringian crossing.

Cluster 2 – Mexico

We find a particularly interesting small cluster of 4 haplogroup O individuals in interior Mexico.

In the 1500s, Spain established a trade route between Mexico and Manilla in the Philippines.

In 1564, four ships left Mexico to cross the Pacific to claim Guam and the Philippines for King Philip II of Spain. The spice trade, back and forth between Mexico and the Philippines began the following year and continued for the next 250.

Landings occurred along the California coast and the western Mexican coastline. The majority of the galleon crews were Malaysian and Filipino who were paid less than the Spanish sailors. Slaves, including people from the Marianas were part of the lucrative cargo.

One individual in Texas reports haplogroup O and indicates their paternal ancestors were Hispanic/Native from Mexico. A haplogroup O cluster claiming Native heritage is found near Zacatecas, Fresnillo and San Luis Potosi in central Mexico. Additionally, mitochondrial haplogroup F, also Asian, is found there as well. Acapulco is the lime green pin.

An additional haplogroup O tester with Native heritage is found in Lima, Peru.

Haplogroup O men are found in Panama, Jamaica and Cuba, but do not indicate the heritage of their paternal ancestral line. None of these men have taken Big-Y tests, and some may well have arrived on the slave ships from Madagascar, especially in the Caribbean. This source attributes some enslaved people in Jamaica to Hawaiian voyages.

I strongly suspect that the Mexican/Peru grouping in close proximity to the Pacific coastline is the result of the Manilla-Mexico 250-year trade route. The Spanish also plied those waters regularly. Big Y testing of those men would help flesh-out their stories – when and how haplogroup O arrived in the local population.

Cluster 3 – East Coast

At first glance, the East Coast grouping of men with a genetic affinity to the people of the Philippines and Indonesia seems more difficult to explain, but perhaps not.

On the East Coast, we have confirmed reports of whalers near Nantucket as early as 1765 utilizing crewmen from Hawaii, known then as the Sandwich Islands, Tahiti, and the Cape Verde Islands off of Africa. A thorough review of early literature might well reveal additional information about early connections with the Sandwich Islands, and in particular, sailors, crew, or enslaved people.

The Spanish and French were the first to colonize the Philippines by the late 1500s. They had discovered the Solomon Islands, Melanesia, and other Polynesian Islands, and by the early 1600s, the Dutch were involved as well.

The Encyclopedia Britanica further reports that Vasco Balboa first sailed into the Pacific in 1513 and seven years later, Ferdinand Magellan rounded the tip of South America. The Spanish followed, establishing a galley trade between Manila, in the Philippines and Acapulco in western Mexico.

While I found nothing specific stating that the earliest voyages brought men from the Philippines and Oceania back to their European home ports with them, we know that early European captains on exploratory voyages took Native people from the east coast of the Americas on their return journey, so there’s nothing to preclude them from doing the same from the Pacific. The early explorers stayed for months among the Oceanic Native peoples. If they were short on sailors for their return voyage, Polynesian men filled the void.

We know that the Spanish took slaves as part of their trade. We know that the ships in the Pacific took sailors from the islands. If the men themselves didn’t stay in the locations they visited, it’s certainly within the realm of possibility that they fathered children with local, Native women. Furthermore, given that the slave trade was lucrative, it’s also possible that some Pacific Island slaves were taken not as crew but with the intention of being sold into bondage. Other men may have escaped the ships and hidden among the Native Tribes along the eastern seaboard.

Fishing in Newfoundland and exploration in what would become the US was occurring by 1500, so it’s certainly possible that some of the indigenous people from Indonesia and the Philippines were either stranded, sold to enslavers, escaped, or chose to join the Native people along the coastline in North America. Ships had to stop to resupply rations and take on fresh water.

We know that by the mid-1600s, James Revels, whose father carried haplogroup O, had been born on the Atlantic coast of Virginia or Maryland, probably on the Delmarva Peninsula, short for Delaware, Maryland, Virginia, where the Accomac people lived.

There are other instances of haplogroup O found along the east coast.

On the eastern portion of the haplogroup O map from the book, DNA for Native American Genealogy, we find the following locations:

  • Hillburn, NY – man identified as “Native American Black.”
  • Chichester County, PA – Genographic tester identified the location of his earliest known ancestor – included here because O is not typically found in the states.
  • Accomack County, VA – Delmarva peninsula – James Revels lineage
  • Robeson County, NC – Lewis and Revels surname associated with the Lumbee
  • Chatham County, NC – Lynn ancestor’s earliest known location
  • Greene County, NC – enslaved Blount ancestor’s EKA in 1849

The genesis of Mr. Blount’s enslaved ancestor is unclear. Fortunately, he took a Big Y-700 test.

Mr. Blount’s only Big-Y match is to a man from the United Arab Emirates (UAE), but the haplogroup history includes Thailand, which is the likely source of both his and his UAE matches’ ancestors at some point in time. Their common ancestor was in Thailand in 336 CE, almost 1700 years ago.

All surrounding branches of haplogroup O on the Time Tree have Asian testers, except for the one UAE gentleman.

The Blount Haplogroup O-FTC77008 does not connect with the common ancestral haplogroup of Lynn and Revels, so these lineages are only related someplace in Oceana prior to O-F265, or more about  30,000 years ago. Their only commonality other than their Asian origins is that they arrived on the East Coast of the Americas.

We know that the Spanish were exploring the Atlantic coastline in the 1500s and were attempting to establish colonies. In 1566, a Spanish expedition reached the Delmarva Peninsula. This spit of land was contested and changed hands several times, belonging variously to the Spanish, Dutch, and British by 1664.

Furthermore, we also know that the ships were utilizing slave labor. One of the Spanish ships wrecked in the waters off North Carolina near Hatteras or Roanoke Island before the Lost Colony was abandoned on Roanoke Island in 1587. The Croatan Indians reported that in memorable history, several men, some of whom were reported to be slaves, had survived the wreck and “disappeared” into the hinterlands – clearly running for their lives.

These men, if they survived, would have been incorporated into the Native population as there were no other settlements at the time. Variations of this scenario may have played out many times.

James Revels’ ancestor could have arrived on any ship, beginning with exploration and colonization in the early 1500s through the mid-1650s.

By the time the chief bound the Indian boy who was given the English name James to Edward Revell, James’s Oceanic paternal ancestor could have been 4, 5 or 6 generations in the past – or could have been his father.

The Accomack was a small tribe, loosely affiliated with the Powhatan Confederacy along the Eastern Shore. By 1700, their population had declined by approximately 90% due to disease. A subgroup, the Gingaskins, intermarried with African Americans living nearby. After Nat Turner’s slave rebellion of 1831, they were expelled from their homelands.

The swamps near Lumberton in Robeson County, NC, became a safe haven for many mixed-race Native, African, and European people. The swamps protected them, and they existed, more or less undisturbed, for decades. Revels and Lewis descendants are both found there.

Many Native Americans were permanently enslaved alongside African people – and within a generation or so, their descendants knew they were Native and African, but lost track of which ancestors descended from which groups. Life was extremely difficult back then. Generations were short, and enslaved people were moved from place to place and sold indiscriminately, severing their family ties entirely, including heritage stories.

Returning to the Discover Time Tree Maps

Wesley Revels has STR matches with several men from Indonesia, China, and the Philippines. It would be very helpful if those men would upgrade to the Big Y-700 so that we can more fully complete the haplogroup O branches of the Time Tree.

The common Revels/Lewis ancestor, accompanied by two descendant men on different genetic branches from the Philippines, was born about 5180 years ago. There is no evidence to suggest Haplogroup O-FT11768 was born anyplace other than in the Philippines.

How did the descendant haplogroups of O-FT45548 (Revels, Lewis, and an unnamed man) and O-F22410 (Lynn) arrive in Virginia or anyplace along the Atlantic seaboard?

Hawaii wasn’t settled until about 1600 years ago. We know Hawaiians integrated with the Pacific Coast Native tribes in the 1800s, but James Revels was in Virginia in 1656..

We know that the Spanish established a mid-1500s trade route between Manila and Acapulco, leaving their genetic signature in western Mexico.

None of these events fit the narrative for the Revels or the Lynn paternal ancestor.

Furthermore, the Revels and Lynn lines do not connect on North American soil, as both descend from the same parent haplogroup, O-FT11768, 5180 years ago in the Philippines. This location and history suggest a connection with the Spanish galleon trade era. The haplogroup formation clearly predates that trade, which means those men were still in the Philippines, not already living on the American continents. Therefore, the descendants of the haplogroup O-FT11768 arrived in Virginia and North Carolina sometime after that haplogroup formation 5100 years ago.

The Lynn ancestor connects with a man from Singapore in 760 CE, or just 1240 years ago. A descendant of haplogroup O-F22410 arrived in North Carolina sometime later.

It does not appear, at least not on the surface, that there is a connection through Madagascar, although we can’t rule that out without additional testers. If the connection is through Madagascar, then their ancestors were likely transported from Indonesia to Madagascar, then as enslaved people from Madagascar to the Atlantic colonies to be sold. However, James Revels was not enslaved. He was clearly Native and bound to a European plantation owner, who did, in fact, free him as agreed and subsequently loaned him money.

Based on the dates involved, and when we know they were in Oceania, an arrival along the west coast, followed by a quick migration across the country to a peninsula of land in the Atlantic, is probably the least likely scenario. There is also no historical or ancient haplogroup O DNA found anyplace between the west and east coasts, nor in the Inuit or Na-Dene speakers. The Navajo, who speak the Na-Dené language, migrated to the Southwest US around 1400 CE, but haplogroup O has not been found among Na-Dené speakers.

It’s a long way from Singapore and the Philippines to Madagascar, so while the coastal migration scenario is not impossible, it’s also not probable, especially given what we know about the Spanish Pacific trade that existed profitably for 250 years.

However, one haplogroup O subgroup arrived in the UAE by some methodology after 336 CE.

It’s entirely possible, indeed probable, that haplogroup O arrived in the Americas for various reasons, on different paths, in different timeframes.

Haplogroup O was found in people in the Americas after colonization had begun. There has been no ancient Haplogroup O DNA discovered, and there’s evidence indicating that these instances of haplogroup O could not have arrived in any of the known Beringia migrations nor the theorized Coastal or Kelp migration. We know the East Coast Cluster is not a result of the West Coast 19th-century migration because James Revels was in court one hundred and fifty years before the Hawaiians were living among the Native people along the Pacific coastline.

There’s nothing to indicate that the Mexican group that likely arrived beginning in the mid-1500s for the next 250 years as a result of the Indonesian trade route migrated to the east coast, or vice versa. That’s also highly unlikely.

The most likely scenario is that Mr. Lynn’s, Mr. Blount’s, and James Revels’ ancestors were brought on trade ships, either as sailors or enslaved men. They may not have stayed, simply visited. They may each have arrived in a completely different scenario, meaning Mr. Blount’s ancestors could have been enslaved arrivals from Madagascar, Mr. Lynn’s from Indonesia, and Mr. Revel’s as a crew member on a Spanish ship. We simply don’t know.

James Revels’ descendants were Native through his mother’s tribe, as confirmed in the 1667 court records. However, the Revels and Lynn lineages weren’t Native as a result of their paternal haplogroup O ancestors crossing Beringia into the Americas with Native American haplogroups Q and C. Instead, the Lynn and Revels migration story is quite different. Their ancestors arrived by ship. The journey was long, perilous, and far more unique than we could have imagined, taking them halfway around the world by water.

Timeline

There’s a lot of information to digest, so I’ve compiled a timeline incorporating both genetic and historical information for easy reference.

Conclusions

It’s without question that James Revels was Native American very early in the settlement of the Delmarva Peninsula, now Accomack County, Virginia, but his common ancestor with Filipino men 5100 years ago precludes his direct paternal ancestor’s presence in the Americas at that time. In other words, his Revel male ancestor did not arrive in the Beringian indigenous migration 12,000-16,000 years ago. His ancestor likely arrived post-contact, based on a combination of both historical and genetic evidence.

Haplogroup O is not found in the Arctic Inuit nor the Na-Dene speakers, precluding a connection with either group, and has never been found in ancient DNA in the Americas.

Haplogroup O in the Revels lineage is most likely connected with the Spanish galleon trade with the Philippines and the early Spanish attempts to colonize the Americas.

The source of Haplogroup O in the Pacific Northwest group is likely found in the recruitment of Hawaiian men in the early/mid-1800s.

The Mexican Haplogroup O group likely originated with the Manilla/Mexico Spanish galleon trade.

The source of the Blount Haplogroup O remains uncertain, other than to say it originated in Thailand thousands of years ago and is also found in the UAE. The common Blount, UAE, and Thailand ancestor’s haplogroup dates to 336 CE, so they were all likely in or near Thailand at that date, about 1687 years ago.

What’s Next?

Science continuously evolves, revealing new details as we learn more, often clarifying or shifting our knowledge. Before the Discover tool provided haplogroup ages based on tests from men around the world, we didn’t have the necessary haplogroup origin and age data to understand the genesis of haplogroup O in the Americas. Now, we do, but there is invariably more to learn.

New evidence is always welcome and builds our knowledge base. Haplogroup O ancient DNA findings would be especially relevant and could further refine what we know, depending on the location, dates of the remains, who they match, and historical context.

Additional Big Y-700 tests of haplogroup O men, especially those with known genealogy or ancestor location, including Madagascar, would be very beneficial and allow the haplogroup formation dates to be further refined.

If you are a male with haplogroup O, please consider upgrading to the Big Y-700 test, here.

Étienne Hebert (c1625-c1670): Two French Brothers & Their Ancient Ancestors – 52 Ancestors #413

In the book, Les vielles familles d’Yamachiche: vingt-trois généalogies, v. 4 published in 1908 in Ontario, we discover that Étienne Hebert is one of two brothers who came from France and settled in Acadia, now Nova Scotia. Étienne married Marie Gaudet and Antoine Hebert married Genevieve LeFranc.

We know that Étienne and Antoine were brothers because in the 2nd marriage record for Jean-Jacques Hébert (1681-?) to Marguerite Leprince on April 27, 1734, at Saint-Charles-les-Mines, they were granted a dispensation from a 3rd degree consanguine relationship. The only overlap in their two family trees would be the parents of Étienne and Antoine Hebert.

Thank goodness for those church records.

Origins

Stephen A. White provided the following information about Étienne.

HÉBERT, Étienne, came from France with his wife Marie Gaudet, according to nine depositions: one from his grandson Jean Hébert (Doc. inéd., Vol. III, p. 11), one from Pierre Trahan, husband of his granddaughter Madeleine Comeau (ibid., p. 8), one from Pierre and Madeleine’s son Pierre Trahan (ibid., pp. 110-111) and one from their nephews Sylvestre and Simon Trahan (ibid., p. 30), two from husbands of Étienne’s great-granddaughters (ibid., Vol. II, p. 182; Vol. III, p. 90), one from a great-great-grandson (ibid., Vol. III, pp. 93-94), and two from husbands of his great-great-granddaughters (ibid., pp. 45, 92-93). Seven of these depositions name his wife as Marie Gaudet; only those of the two Pierre Trahans, father and son, do not.

Lucy LeBlanc Consentino documents these priceless depositions here.

Parents

There have been several proposed and presumed parents of Étienne and Antoine Hebert. None are proven, and some have been disproven. I’m not going to recount each theory here. I’ll briefly mention the most common ones and strongly suggest that anyone tempted to assign parents for these men consult existing resources and arguments first.

Tim Hebert’s website is no longer online, but you can view it here at Wayback Machine. Tim did an exceptional job documenting the various theories and Hebert descendants.

It has been said that possibly the brothers were from south of Loudon (LaChaussee, Martaize, etc.), however, since Charles Menou d’Aulnay’s family had land in that vicinity. If he recruited settlers from that area, there is a chance they came from there, but there is no proof of where they (or most other) Acadians came from. The linguistic studies by Genevieve Massignon tried to say that they were from the Loudon area, but perhaps she was focusing too much. It is probably true that they came from western France. But the lack of documentation in the Loudon region means that perhaps we’re looking in the wrong place. Michael Poirier has suggested they came from west of Loudon at the coast … near Baie de Bourgneuf.

He bases this on:
– the location of the monastery of the Assumption (on the island Chauvet), which was regularly attended by Richelieu and was the property of his brother, Alphonse.
– Port-Royal and the church of St Jean-Baptiste
– salt-water marshes in the area were drained … much like the dyke system utilized in Acadia
– it was a zone surrounded by Protestants and enclosing Catholics

Genevieve Massignon (1921-1966) argues that a number of familial alliances existed among the first Acadian settlers PRIOR to their arrival from France, pointing to a common French origin. She believes they lived in the Acadian Governor d’Aulnay’s seigneury in France near Loudun (comprised of the villages of Angliers, Aulnay, Martaizé, and La Chausée). The Hébert family was allied with the Gaudets through Étienne’s marriage to Marie. Marie’s sister Francoise was also allied with the Leblanc family through her marriage to Daniel. Evidence of their marriages in France is found in the Belle-Isle-en-Mer declarations in 1767. Moreover, a certain Jean Gaudet was censistaire in 1634 on land at Martaizé (Vienne) in the Seigneurie owned by the mother of Acadian governor Charles d’Aulnay. However, Massignon’s research failed to find any relevant baptismal or marriage records.

Another couple, Jacques Hebert and Marie Juneau have been debunked as parents, based on the date of their marriage and analysis by Stephen White. Jacques was found in Acadia 30 years before Étienne and Antoine, then moved into mainland Canada. It’s unlikely that his two sons would be found in Acadia and not near or with him. Not to mention the depositions that state that Étienne and Antoine were born in France.

Another parent candidate was Louis Habert who is generally considered to have been the first permanent settler in Canada, arriving in 1604. He married Marie Rolet in Paris in 1602 but wasn’t known to live in Acadia. Spelling variations of this family name include Hebert, Harbert, Herbert, Herbot, Harbelot, and others. You can read more about this at FamilySearch here.

One source stated that Stephen White reported that Etienne Hebert arrived on the ship, La Verge in 1648. Karen Theriot Reader, upon further examination, determined that the page given as the source does not in fact provide that information, nor elsewhere by White.

However, the Verve did arrive in 1648, chartered by Emmanuel LeBorgne, Sieur of Coudray, to transport supplies. No passenger list exists, and several ships arrived in Acadia over the years.

In a letter to Tim Hebert, Stephen White stated that their parents are “unknown.” No birth records have been found, and White found none of the proposed parents convincing or even probable.

We simply don’t know when and where Étienne and Antoine were born. It’s fair to say it was in France because families weren’t imported until 1636. The Hebert brothers were born in the 1620s. They would have been teenagers or young men in 1636.

What Was Happening in Acadia?

Warm up your tea or coffee, ‘cause this is a fascinating tale.

Acadia was truly the frontier and constantly caught in the middle in a tug of war between France and England for control of both the land and resources, along with the people.

Settlement in Acadia began in 1604, but we’re joining this history 28 years later.

In 1632, control of Acadia passed from the English back to the French, who immediately launched voyages transporting traders and workers, some of whom became settlers. Their initial goal wasn’t settlement, though, but trading posts.

Port Royal is shown on Champlain’s 1632 map.

Isaac de Razilly was a French noble sea captain and knight who convinced his cousin, Cardinal Richelieu, chief minister to the King of France, that colonizing and establishing fur trade with Acadia was a profitable business venture. As a bonus that probably sounded attractive to Richelieu, they could convert and baptize the Native people, too.

Razilly’s 1632 voyage on the L’Esperance a Dieu included about 300 people, mostly men with possibly 12-15 women. A French newspaper report from that time states that a third ship from Rochelle joined the other two. A mason, baker, nailmaker-blacksmith, joiners, gunsmiths, sawyers, laborers, and soldiers signed up.

In 1640, notarial records in La Rochelle, France, show many contracts of engagement for workers in Acadia, although most of those people aren’t shown in the 1671 census, meaning they either died or returned to France when their engagement was over. In 1640, at least 25 men and 5 women signed up.

Couillard-Despres in “Les Gouvernors” states that 63 men arrived on the Saint Clement in 1642 to assist Charles LaTour.

After Razilly’s death in 1635, his cousin, Charles de Menou d’Aulnay, de Charnisay prepared to take over the administration of Acadia. By this time, there were 44 inhabitants at Le Have, Razily’s base of operation. Sometime between 1635 and 1640, d’Aulnay moved the settlement to Port Royal, but the men who had married Native American women likely did not move with him.

However, Charles La Tour, who had lived in Acadia since he was 17 and was married to a Mi’kmaq woman, had other plans. His father, Claude, obtained a grant for Nova Scotia from the English king, and Charles was appointed Governor, serving from 1631-1642. In essence, the LaTour father-son duo had outsmarted d’Aulnay.

Workers still continued to arrive. The 1636 passenger list of the St. Jehan, including occupations and some location origins, still exists.

d’Aulnay and La Tour began as competitors, with LaTour working out of Cap Sable and the St. John River area with traders, and d’Aulnay, who moved the Acadian settlement from La Have to Port Royal, beginning cultivation. Given where we find Étienne Hebert living, he likely arrived with d’Aulnay.

However, the competition between those men soon became animosity, then open warfare, with both men claiming to be in charge of all of Acadia.

If you think there was no drama in a relatively unpopulated area, just try to keep this next bit straight.

In 1640, after LaTour’s Mi’kmaq wife died, he married a French Huguenot woman, Françoise-Marie Jacquelin, who had powerful connections.

In 1642, d’Aulnay had LaTour, a Huguenot, charged with treason against France. LaTour’s well-connected wife traveled to France to advocate on behalf of her husband, returning with a warship for him to defend himself.

Perhaps this was a bit hasty.

In the Spring of 1643, La Tour led a party of English mercenaries against the French Acadian colony at Port-Royal. His 270 Puritan and Huguenot troops killed three men, burned a mill, slaughtered cattle, and seized 18,000 livres worth of furs.

Apparently, LaTour was a traitor after all, at least from the French perspective.

LaTour then traveled to Boston seeking reinforcements from the English, and while he was gone, d’Aulnay seized all of his possessions and outposts, including Fort LaTour.

Are you keeping track of this? I think the score was 3 to 3 here, with a Hail Mary pass underway. Get the popcorn.

LaTour may have been traveling to Boston, but his wife, Françoise-Marie, had remained at home and was not about to relinquish Fort LaTour without a fight.

In the ensuing battle, Françoise-Marie, at the ripe old age of 23, defended Fort LaTour in the Battle of St. John for three days, using the warship. D’Aulnay lost 33 men but on the fourth day, was able to capture the fort. LaTour’s men were hung at the gallows as Françoise-Marie was forced to watch with a rope around her neck, just in case she got any bright ideas. She was clearly not a woman to be trifled with.

Françoise-Marie was not hung, but Nicolas Denys recorded in his journal that she died three weeks later as a prisoner in captivity. The cause remains unknown, but it’s safe to say that her death was a volley in war. 

After learning that his wife had died, his possessions confiscated, and his men killed, LaTour sought refuge in Quebec City. He did not return to Acadia for several years, but return he would – eventually.

For the time being, d’Aulnay was firmly in control, but that only lasted a few years.

In 1650, d’Aulnay drowned when his canoe overturned, which provided the opening LaTour had been waiting for. LaTour sailed to France, obtained royal favor, his property restored, and returned to Acadia as governor in 1653, accompanied by several new colonists, including Philippe Mius d’Entremont, 1st Baron of Pobomcoup.

It was about this time, around 1650, that Étienne Hebert married Marie Gaudet. Perhaps they hoped that living near her parents, a dozen miles upriver, would be more peaceful and less exposed to attack and conflict.

LaTour had remained a widower since his wife’s death defending Fort LaTour in 1645, but in 1653, he married…wait for it… d’Aulnay’s widow, Jeanne Motin. It was not a marriage in name only, as they had five children. Some said they married to heal the rift between the warring d’Aulnay and LaTour camps, some think it was simply a marriage of convenience for both, and others feel it was LaTour’s final victory over d’Aulnay. However, Jeanne was no shrinking violet because she evicted Nicolas Denys when he attempted to exploit d’Aulnay’s death by setting up trading posts at St. Ann and St. Peters.

LaTour wasn’t off the hook, though, because in an odd sort of way, d’Aulnay still managed to be a thorn in LaTour’s side – even from beyond the grave.

Along with d’Aulnay’s property and wife came his substantial debts to Emmanuel Le Borgne, his main financier from La Rochelle. There were two sides to this story because, as part of the deal, La Bourg and other seigneurs were supposed to recruit and transport new settlers to Acadia and care for them by building communal resources like mills and bake-ovens, but they didn’t.

It appears that the Acadians and their French sponsors were both relatively unhappy. The French did not live up to their end of the bargain by building mills and ovens, and consequently, the Acadians resisted paying taxes. Everyone resented the English, but the English needed the Acadian settlers to work the land. And, of course, the land passed back and forth between the French and English from time to time, punctuated by skirmishes and outright attacks.

Acadia, for an Atlantic peninsula of land with few people, was drama-central.

By 1653, it was estimated that there were 45-50 households at Port Royal and La Have, which provides us an estimate of 300-350 people, including 60 single men. Étienne Hebert was lucky to find a bride, any bride.

In 1654, Port Royal was still small, with approximately 270 residents, as estimated by pioneer Nicholas Denys. Denys was a French prisoner at Port Royal who had been responsible for recruiting volunteers for the 1632 Razilly expedition of 300 men from Rochelle, France. They landed at La Hève near modern Bridgewater, the eventual site of the Gaudet village. This location was near the upper reaches of the tidal portion of the Riviere du Dauphine, and their boat probably could not progress further.

Denys did us the favor of describing Port Royal in 1653:

There are numbers of meadows on both shores, and two islands which possess meadows, and which are 3 or 4 leagues from the fort in ascending. There is a great extent of meadows which the sea used to cover, and which the Sieur d’Aulnay had drained. It bears now fine and good wheat, and since the English have been masters of the country, the residents who were lodged near the fort have for the most part abandoned there houses and have gone to settle on the upper part of the river. They have made their clearings below and above this great meadow, which belongs at present to Madame de La Tour. There they have again drained other lands which bear wheat in much greater abundance than those which they cultivated round the fort, good though those were. All the inhabitants there are the ones whome Monsieur le Commandeur de Razilly had brought from France to La Have; since that time they have multiplied much at Port Royal, where they have a great number of cattle and swine.

The commentary about the French settling on the upper part of the river may be very important for the Hebert family because that’s exactly where they are found.

Denys also recorded that Robert Sedgewick of Boston had been ordered by Robert Cromwell to attack New Holland (New York). As Sedgewick prepared, a peace treaty was signed between the English and the Dutch. Since he was “all dressed up with nowhere to go,” he attacked Acadia in August 1654 and destroyed most of the settlements, including Port Royal, La Have, and the Saint John River village. Sedgewick left the area but appointed an Acadian council with Guillaume Trahan in charge. Some of the French may have returned to France at this point.

Denys doesn’t say if Sedgewick burned the upper river homesteads and farms or if he was satisfied with torching Port Royal. Living 12-14 miles away in the out-country may have been the saving grace of the Hebert and Gaudet families. Or, their homesteads and farms may have been destroyed, too. Certainly, if not burned out, they were devastated by Acadia falling to the English.

Acadia was back under English rule and would remain so until being returned, again, to the French in 1667.

After Sedgewick captured Acadia for the English, LaTour went to London to regain his property, again. Being a Protestant would have worked in his favor, as well as having led the English in raids against Port Royal in 1643.

In 1656, Cromwell granted property to two Englishmen and LaTour, but LaTour sold his share to the Englishmen and moved to Cap Sable, on the southern end of the peninsula, to attempt to live the rest of his life in peace.

We don’t know positively that the Hebert brothers were in Acadia at this time, but it’s almost assured. They had probably been in Acadia for between 10 and 30 years. If White is correct, they had resided in Acadia for eight years. Windows of immigration existed, but generally only when the French were in charge, although France imported settlers to other nearby parts of New France. The French were not imported directly into Acadia when the English ruled.

In 1666, France stopped sending colonists, ostensibly for fear of depopulating the mother-country. However, the English were still arriving in the colonies to escape religious prosecution and for economic reasons. Therefore, the Acadians were exposed to at least some English settlers, probably spoke and understood at least a little English, and established some level of trade with the English colonies along the Eastern seaboard.

Given the 1671 census and the ages of his children, we know Étienne was married by 1651 and that his wife’s parents also settled in Acadia.

Life in Acadia always seemed to be contentious and apparently, in no small part, dangerous.

Étienne was probably in his mid to late 40s when he died, about 1670. He clearly didn’t die of old age, but probably as a result of hunting, fishing, or farming – some accident. Or, perhaps, there was a skirmish. It seemed like there was always some sort of skirmish, but a simple act of daily living such as fishing carried the risk of drowning.

The Catholic church records don’t exist, if they even had a priest at that time, so we don’t know when Étienne died. We can rest assured that, if possible, he was buried in the parish cemetery, now the Garrison Cemetery in Annapolis Royal, beside the fort and the Catholic church.

The First Acadian Census

Even though Acadia was officially returned to France in 1667, it didn’t actually happen right away. In 1670, the English surrendered the fort at Port Royal, apparently without incident. The new French governor arrived, bringing with him another 60 settlers and 30 soldiers. The new governor ordered a census, thankfully. He likely needed to know how many people would be paying taxes.

The first Acadian census was taken in 1671, documenting between 240 and 350  Acadian residents (depending which count you utilize) in 68 households in Port Royal and one household each in three other locations. Historians know some residents in settlements weren’t counted, and neither were Acadian/Native American families living with the Native people. Estimates of the entire Acadian population reach as high as 500.

Étienne was already deceased, but we can tell quite a bit from his widow’s census record, transcribed here by Lucy LeBlanc Consentino.

Marie Gaudet, widow of Étienne Hebert, 38. She has 10 children, two married children: Marie 20, Marguerite 19; Emmanuel 18, not yet married, Étienne 17, Jean 13, Francoise 10, Catherine 9, Martine 6, Michel 5, Antoine 1, 4 cattle, 5 sheep and 3 arpents of cultivated land.

This tells us that Etienne and Marie were married in about 1650, or maybe somewhat earlier. Their eldest living child was age 20. Étienne was probably about 25 years old when he married, so I’d estimate his birth year as 1625, give or take a few years. It appears that Marie Gaudet and her daughter, Marie Hebert, and her husband, Michel de Forest, and their families were probably living either on the same farm or even in the same house.

Marie’s youngest child was age 1, so we know that Étienne died sometime between 1669 and 1671.

His brother, Antoine Hebert is listed three houses away as a 50-year-old cooper, so he was born about 1621.

Hebert and Gaudet Allied Families

It’s clear that the Hebert family was somehow allied with the Gaudet family as early as 1650 when their children married. It’s possible that they married in France, or Acadia.

What we do know is that these two families lived in close proximity on the Riviere de Dauphine, now the Annapolis River.

This 1733 map at the Nova Scotia Archives is based on the 1707 census route and shows about a mile and a half or two miles distance between the Hebert and Gaudet homesteads – 57 years after Étienne Hebert and Marie Gaudet married.

Etienne Hebert lived along Bloody Creek, where the Hebert Village is found, courtesy of MapAnnapolis, below.

We know where Etienne, Marie, and their family lived and at least something about their life – but what else can we unearth?

The Hebert DNA Story

Eventually, the answer to where the Hebert brothers originated in France will be told through their Y-DNA, passed directly from father to son through the generations without ever being admixed with the mother’s DNA, or divided.

The Hebert family is well-represented in the Acadian AmerIndian Project with three Big-Y testers showing the same haplogroup. Haplogroup R-BY31006 was born about 1650, almost exactly when Étienne and his brother were marrying and having children near Fort Royal.

Two present-day project members descend from Étienne, and one descends from Étienne’s brother, Antoine. They have the same high-resolution haplogroup, so we know that their father had the same mutation that he gave to both sons. How I wish some Hebert men from France could test, but DNA testing for genealogy is illegal there.

Unfortunately, no other contemporary man of any surname is close to our Hebert cluster. The haplogroup ancestor upstream of R-BY31006 is the parent haplogroup R-BY31008 that occurred about 245 BCE, or 2245 years ago. The descendants of that man are also found in England, Norway, and Scotland, in addition to our Hebert men in France.

That’s quite interesting.

But there’s something even more interesting.

Ancient DNA

Looking at Ancient Connections in Discover, I note that one of the Hebert Ancient Connections was found in France and has been placed into haplogroup R-Z31644. I wonder what the connection is. Let’s take a look at that haplogroup.

The TimeTree shows us that nine ancient DNA samples are found on different haplogroup branches of R-Z31644, of which only one is found in Metz, France, and the rest in the British Isles. It’s unclear exactly what this means. Only the French sample and three others in England and Ireland are found in the current era, meaning after 1 CE. This was clearly prior to the Battle of Hastings in 1066, after which an influx of French settled in England.

Eight ancient DNA results are found in England, but none share a common ancestor earlier than 4300 years ago. Notably, one English burial from about 2000-2300 years ago shares a common ancestor with the Metz, France remains about 4000 years ago. The eight English remains, and our Metz guy descend from a common ancestor about 4300 years ago.

Did Étienne’s ancestors descend from the ancient sample at Metz? Maybe the study provides more clues.

According to the study’s authors:

The Sablon district, which is located in the southern part of the city of Metz, was, during the Gallo-Roman period, a huge necropolis where both inhumations and cremations are found. Towards the end of the 19th century, the exploitation of the sandpits enabled the uncovering of sarcophagi (stone), cists (brick and tile), coffins (wood) and vats (lead).

These characterise the new burial practices developed during late Antiquity. [Spans from about the 3rd to the 6th or 7th centuries.]

The largest funerary space spans almost a kilometre, on either side of the via Scarponensis (portion of the Reims/Metz road).

The Sablon area can be compared to the Collatina necropolis close to Rome by its chaotic organisation, although at a different scale

Looking at a map of Metz helps put this in context.

It’s unclear exactly where along this route the burials were discovered beginning in the late 1800s. They extend for more than a kilometer on both sides of the road in the Sablon neighborhood of Metz.

The Sablon neighborhood extends from near the old city center along the main artery that crosses railroad tracks that appear to sever the original road into the city.

Does the history of Metz tell us who lived there and what was occurring during this time? Indeed, it does.

Metz is located at the confluence of the Moselle and Seille rivers, near the junction of France, Germany, and Luxembourg. The original inhabitants were Celtic. The town was known as the “city of Mediomatrici,” a fortified city of the tribe by the same name.

The Mediomatrici village evolved into a Gallo-Celtic city after Julius Caesar conquered the Gauls in 52 BCE.

Named Divodurum Mediomatricum by the Romans, present-day Metz was integrated into the Roman empire in the first century CE, after which it was colloquially referred to as the Holy Village.

The historic district has kept part of the Gallo-Roman city with Divodurum’s Cardo Maximus, then called Via Scarponensis. Today, this is Trinitaires, Taison, and Serpenoise streets in the old city center, and the Decumanus Maximus, which is En Fournirue and d’Estrées streets. The Roman Forum was located at the Cardo and Decumanus intersection and is the Saint-Jacques Square today, as shown below.

The ancient burial occurred between 432 and 551 CE, as calculated from a molar and was found in a very large Gallo-Roman necropolis, more than a kilometer long, located on both sides along the old Roman road.

This cityscape shows Divodurum Mediomatricum in the second century CE, capital of the Mediomatrici, ancestor city of present-day Metz. The original Roman amphitheater is shown at far left, and the living quarters are located within the city walls, protecting them from attack. A wonderful summary of archaeological findings can be found here.

Today the the Centre Pompidou-Metzocation is found at the site of the original large Roman amphitheater. This amphitheater held upwards of 25,000 people and was the largest and most consequential amphitheater outside of Rome.

Rome’s influence ended when the city was attacked, pillaged and burned by the Huns on April 7, 451, then passed into the hands of the Franks about 50 years later. By 511, Metz was the capital of the Kingdom of Austrasia.

How Does the Metz Burial Connect to England?

How do the dots between Metz and the British Isles connect, given that the common ancestor of our Metz burial and the British Isles burials has descendants scattered throughout the British Isles and in Metz?

The Celts first migrated to the British Isles about 1000 BCE, or about 3000 years ago, so this ancient French man and the other ancient burials in the British Isles make sense. Their common ancestor lived 4300 years ago in Europe. The closest common ancestor of our Metz man and any English burial occurred 4000 years ago, 1000 years before the earliest Celtic migrations across the English Channel.

This man from Metz lived 1500 or 1600 years ago and shares an ancestor with several ancient British men in addition to our Hebert line and was likely Celtic..

Of course, not every Celtic man left Europe. Many stayed and eventually integrated with whoever the next conquering army was. That ensured survival. Metz was a prize to be won, controlled over the centuries by many masters.

We don’t know if this specific Celtic man buried along the Gallo-Roman Road was a direct ancestor to our Hebert line, but if not, they were assuredly related and shared common ancestors. The descendants of haplogroup R-BY31008 are unquestionably the ancestors of our Hebert line.

Back to Étienne

Étienne’s Y-DNA has identified his ancestors as Celtic some 4000 years, or 200 generations ago.

More recently, his Y-DNA confirmed his connection to Antoine Hebert, and the church records of both of their descendants confirmed them as brothers.

Depositions given by Étienne’s grandchildren, spouses of grandchildren, great-grandchildren, nieces, and nephews confirm that Étienne was born in France, but, unfortunately, does not say where. This information alone debunked some of his parent candidates.

We find no suggestion of his parents in Acadia, although that’s not impossible. Many people died and never made it into existing records. The Hebert brothers likely arrived together as young men. Antoine may have married in France, as his wife’s surname is not found in Acadia. Of course, her father could have died and left no record. Étienne’s wife’s family lives next to the Heberts in Acadia, but we don’t know if Étienne and Marie Gaudet married in France or after arrival in Acadia.

How well did Étienne remember France? Did he look over his slice of countryside along the Riviere du Dauphine, with its dikes holding the tidal river at bay, and think of similar dikes constructed by his ancestors in France?

What about his parents?

Did they die, or did he sail away, knowing he and his brother would never see them or their siblings again?

Did their family shrink into tiny dots on the horizon, waving from the wharf, then disappear forever?

Did the brothers leave because they wanted to, or did they leave perhaps because they had no family left? Often, orphans had few options in their home country, and any opportunity was welcomed.

Did Étienne marry Marie Gaudet in Acadia, or did they marry someplace in France, then two Hebert boys immigrating to the new land with the Gaudet family?

In one way, we know so much – that Étienne matches an ancient Celtic burial in Metz who died about 1500 years ago, with whom he shared a common ancestor about 4000 years ago – yet we can’t identify Étienne’s parents. At least not today, but hope springs eternal. Two years ago, we didn’t know this.

Hopefully, one day, DNA testing for genealogy will be available to men in France. Our answers lie in Hebert men in some small French village, probably along a river that was once a highway of history.

Acknowledgments

I’m incredibly grateful to the Hebert men who have taken the Big Y-700 DNA test at FamilyTreeDNA, and to FamilyTreeDNA, because without those tests and the Discover tool that includes ancient DNA connections, we would never be able to peer beyond the mists of time into their deep ancestry.

As more men test and more academic studies and ancient DNA results are added to the Discover database, we’ll continue to learn more. The Big-Y DNA test is the gift that just keeps on giving.

Which DNA Test Should I Buy? And Why?

Which DNA test should I buy, and why?

I receive questions like this often. As a reminder, I don’t take private clients anymore, which means I don’t provide this type of individual consulting or advice. However, I’m doing the next best thing! In this article, I’m sharing the step-by-step process that I utilize to evaluate these questions so you can use the process too.

It’s important to know what questions to ask and how to evaluate each situation to arrive at the best answer for each person.

Here’s the question I received from someone I’ll call John. I’ve modified the wording slightly and changed the names for privacy.

I’m a male, and my mother was born in Charleston, SC. My maternal grandmother’s maiden name was Jones and a paternal surname was Davis. The family was supposed to have been Black, Dutch, Pennsylvania Dutch, and Scots-Irish…only once was I told I was 3/16 Indian, with Davis being 3/4 and Jones being full Indian.

Do I have enough reasonable information to buy a test, and which one?

Please note that it’s common for questions to arrive without all the information you need to provide a sound answer – so it’s up to you to ask those questions and obtain clarification.

Multiple Questions

There are actually multiple questions here, so let me parse this a bit.

  1. John never mentioned what his testing goal was.
  2. He also never exactly said how the paternal line of Davis was connected, so I’ve made an assumption. For educational purposes, it doesn’t matter because we’re going to walk through the evaluation process, which is the same regardless.
  3. John did not include a tree or a link to a tree, so I created a rudimentary tree to sort through this. I need the visuals and normally just sketch it out on paper quickly.
  4. Does John have enough information to purchase a test?
  5. If so, which test?

There is no “one size fits all” answer, so let’s discuss these one by one.

Easy Answers First

The answer to #4 is easy.

Anyone with any amount of information can purchase a DNA test. Adoptees do it all the time, and they have no prior information.

So, yes, John can purchase a test.

The more difficult question is which test, because that answer depends on John’s goals and whether he’s just looking for some quick information or really wants to delve into genealogy and learn. Neither approach is wrong.

Many people think they want a quick answer –  and then quickly figure out that they really want to know much more about their ancestors.

I wrote an article titled DNA Results – First Glances at Ethnicity and Matching for new testers, here.

Goals

Based on what John said, I’m going to presume his goals are probably:

  • To prove or disprove the family oral history of Black, Dutch, Pennsylvania Dutch (which is actually German,) Scots-Irish, and potentially Native American.
  • John didn’t mention actual genealogy, which would include DNA matches and trees, so we will count that as something John is interested in secondarily. However, he may need genealogy records to reach his primary goal.

If you’re thinking, “The process of answering this seemingly easy question is more complex than I thought,” you’d be right.

Ethnicity in General

It sounds like John is interested in ethnicity testing. Lots of people think that “the answer” will be found there – and sometimes they are right. Often not so much. It depends.

The great news is that John really doesn’t need any information at all to take an autosomal DNA test, and it doesn’t matter if the test-taker is male or female.

To calculate each tester’s ethnicity, every testing company compiles their own reference populations, and John will receive different results at each of the major companies. Each company updates their ethnicity results from time to time as well, and they will change.

Additionally, each company provides different tools for their customers.

The ethnicity results at different companies generally won’t match each other exactly, and sometimes the populations look quite different.

Normally, DNA from a specific ancestor can be found for at least 5 or 6 generations. Of course, that means their DNA, along with the DNA from all of your other ancestors is essentially combined in a communal genetic “pot” of your chromosomes, and the DNA testing company needs to sort it out and analyze your DNA for ethnicity.

DNA descended from ancestors, and their populations, further back in people’s trees may not be discerned at all using autosomal DNA tests.

A much more specific “ethnicity” can be obtained for both the Y-DNA line, which is a direct patrilineal line for men (blue arrow,) and the mitochondrial DNA line (pink arrows,) which is a direct matrilineal line for everyone, using those specific tests.

We will discuss both of those tests after we talk about the autosomal tests available from the four major genealogy DNA testing companies. All of these tools can and should be used together.

Let’s Start with Native American

Let’s evaluate the information that John provided.

John was told that he “was 3/16 Indian, with Davis being 3/4 and Jones being full Indian.”

We need to evaluate this part of his question slightly differently.

I discussed this in the article, Ancestral DNA Percentages – How Much of Them is in You?

First, we need to convert generations to 16ths.

You have two ancestors in your parent’s generation, four in your grandparents, and so forth. You have 16 great-great-grandparents. So, if John was 3/16th Native, then three of his great-great-grandparents would have been fully Native, or an equivalent percentage. In other words, six ancestors in that generation could have been half-Native. Based on what John said, they would have come from his mother’s side of the tree. John is fortunate to have that much information to work with.

He told us enough about his tree that we can evaluate the statement that he might be 3/16ths Native.

Here’s the tree I quickly assembled in a spreadsheet based on John’s information.

His father, at left, is not part of the equation based on the information John provided.

On his mother’s side, John said that Grandfather Davis is supposed to be three-quarters Native, which translates to 12/16ths. Please note that it would be extremely beneficial to find a Y-DNA tester from his Davis line, like one of his mother’s brothers, for example.

John said that his Grandmother Jones is supposed to be 100% Native, so 16/16ths.

Added together, those sum to 28/32, which reduces down to 14/16th or 7/8th for John’s mother.

John would have received half of his autosomal DNA from his mother and half from his non-Native father. That means that if John’s father is 100% non-Native, John would be half of 14/16ths or 7/16ths, so just shy of half Native.

Of course, we know that we don’t always receive exactly 50% of each of our ancestors’ DNA (except for our parents,) but we would expect to see something in the ballpark of 40-45% Native for John if his grandmother was 100% Native and his grandfather was 75%.

Using simple logic here, for John’s grandmother to be 100% Native, she would almost assuredly have been a registered tribal member, and the same if his grandfather was 75% Native. I would think that information would be readily available and well-known to the family – so I doubt that this percentage is accurate. It would be easy to check, though, on various census records during their lifetimes where they would likely have been recorded as “Indian.” They might have been in the special “Indian Census” taken and might be living on a reservation.

It should also be relatively easy to find their parents since all family members were listed every ten years in the US beginning with the 1850 census.

The simple answer is that if John’s grandparents had as much Native as reported, he would be more than 3/16th – so both of these factoids cannot simultaneously be accurate. But that does NOT mean neither is accurate.

John could be 7/8th or 40ish%, 3/16th or 18ish%, or some other percentage. Sometimes, where there is smoke, there is fire. And that seems to be the quandary John is seeking to resolve.

Would  Ethnicity/Population Tests Show This Much Native?

Any of the four major testing companies would show Native for someone whose percentage would be in the 40% or 18% ballpark.

The easiest ethnicities to tell apart from one another are continental-level populations. John also stated that he thinks he may also have Black ancestry, plus Dutch, Pennsylvania Dutch (German), and Scots-Irish. It’s certainly possible to verify that using genealogy, but what can DNA testing alone tell us?

How far back can we expect to find ethnicities descending from particular ancestors?

In this table, you can see at each generation how many ancestors you have in that generation, plus the percentage of DNA, on average, you would inherit from each ancestor.

All of the major DNA testing companies can potentially pick up small trace percentages, but they don’t always. Sometimes one company does, and another doesn’t. So, if John has one sixth-generation Native American ancestor, he would carry about 1.56% Native DNA, if any.

  • Sometimes a specific ethnicity is not found because, thanks to random recombination, you didn’t inherit any of that DNA from those ancestors. This is why testing your parents, grandparents, aunts, uncles, and siblings can be very important. They share your same ancestors and may have inherited DNA that you didn’t that’s very relevant to your search.
  • Sometimes it’s not found because the reference populations and algorithms at that testing company aren’t able to detect that population or identify it accurately, especially at trace levels. Every DNA testing company establishes their own reference populations and writes internal, proprietary ethnicity analysis algorithms.
  • Sometimes it’s not found because your ancestor wasn’t Native or from that specific population.
  • Sometimes it’s there, but your population is called something you don’t expect.

For example, you may find Scandinavian when your ancestor was from England or Ireland. The Vikings raided the British Isles, so while some small amount of Scandinavian is not what you expect, that doesn’t mean it‘s wrong. However, if all of your family is from England, it’s not reasonable to have entirely Scandinavian ethnicity results.

It’s also less likely as each generation passes by that the information about their origins gets handed down accurately to following generations. Most non-genealogists don’t know the names of their great-grandparents, let alone where their ancestors were from.

Using a 25-year average generation length, by the 4th generation, shown in the chart above, you have 16 ancestors who lived approximately 100 years before your parents were born, so someplace in the mid-1800s. It’s unlikely for oral history from that time to survive intact. It’s even less likely from a century years earlier, where in the 7th generation, you have 128 total ancestors.

The best way to validate the accuracy of your ethnicity estimates is by researching your genealogy. Of course, you need to take an ethnicity test, or two, in order to have results to validate.

Ethnicity has a lot more to offer than just percentages.

Best Autosomal Tests for Native Ethnicity

Based on my experience with people who have confirmed Native ancestry, the two best tests to detect Native American ethnicity, especially in smaller percentages, are both FamilyTreeDNA and 23andMe.

Click images to enlarge

In addition to percentages, both 23andMe and FamilyTreeDNA provide chromosome painting for ethnicity, along with segment information in download files. In other words, they literally paint your ethnicity results on your chromosomes.

They then provide you with a file with the “addresses” of those ethnicities on your chromosomes, which means you can figure out which ancestors contributed those ethnicity segments.

The person in the example above, a tester at FamilyTreeDNA, is highly admixed with ancestors from European regions, African regions and Native people from South America.

Trace amounts of Native American with a majority of European heritage would appear more like this.

You can use this information to paint your chromosome segments at DNAPainter, along with your matching segments to other testers where you can identify your common ancestors. This is why providing trees is critically important – DNA plus ancestor identification with our matches is how we confirm our ancestry.

This combination allows you to identify which Native (or another ethnicity) segments descended from which ancestors. I was able to determine which ancestor provided that pink Native American segment on chromosome 1 on my mother’s side.

I’ve provided instructions for painting ethnicity segments to identify their origins in specific ancestors, here.

Autosomal and Genealogy

You may have noticed that we’ve now drifted into the genealogy realm of autosomal DNA testing. Ethnicity is nice, but if you want to know who those segments came from, you’ll need:

  • Autosomal test matching to other people
  • To identify your common ancestor with as many matches as you can
  • To match at a company who provides you with segment information for each match
  • To work with DNAPainter, which is very easy

The great news is that you can do all of that using the autosomal tests you took for ethnicity, except at Ancestry who does not provide segment information.

Best Autosomal Test for Matching Other Testers

The best autosomal test for matching may be different for everyone. Let’s look at some of the differentiators and considerations.

If you’re basing a testing recommendation solely on database size, which will probably correlate to more matches, then the DNA testing vendors fall into this order:

If you’re basing that recommendation on the BEST, generally meaning the closest matches for you, there’s no way of knowing ahead of time. At each of the four DNA testing companies, I have very good matches who have not tested elsewhere. If I weren’t in all four databases, I would have missed many valuable matches.

If you’re basing that recommendation on which vendor began testing earliest, meaning they have many tests from people who are now deceased, so you won’t find their autosomal tests in other databases that don’t accept uploads, the recommended testing company order would be:

If you’re basing that recommendation on matches to people who live in other countries, the order would be:

Ancestry and 23andMe are very distant third/fourth because they did not sell widely outside the US initially and still don’t sell in as many countries as the others, meaning their testers’ geography is more limited. However, Ancestry is also prevalent in the UK.

If you’re basing that recommendation on segment information and advanced tools that allow you to triangulate and confirm your genetic link to specific ancestors, the order would be:

Ancestry does NOT provide any segment information.

If you’re basing that recommendation on unique tools provided by each vendor, every vendor has something very beneficial that the others don’t.

In other words, there’s really no clear-cut answer for which single autosomal DNA test to order. The real answer is to be sure you’re fishing in all the ponds. The fish are not the same. Unique people test at each of those companies daily who will never be found in the other databases.

Test at or upload your DNA to all four DNA testing companies, plus GEDmatch. Step-by-step instructions for downloading your raw data file and uploading it to the DNA testing companies who accept uploads can be found, here.

Test or Upload

Not all testing companies accept uploads of raw autosomal DNA data files from other companies. The good news is that some do, and it’s free to upload and receive matches.

Two major DNA testing companies DO NOT accept uploads from other companies. In other words, you have to test at that company:

Two testing companies DO accept uploads from the other three companies. Uploads and matching are free, and advanced features can be unlocked very cost effectively.

  • FamilyTreeDNA – free matching and $19 unlock for advanced features
  • MyHeritage – free matching and $29 unlock.for advanced features

I recommend testing at both 23andMe and Ancestry and uploading one of those files to both FamilyTreeDNA and MyHeritage, then purchasing the respective unlocks.

GEDmatch

GEDmatch is a third-party matching site, not a DNA testing company. Consider uploading to GEDmatch because you may find matches from Ancestry who have uploaded to GEDmatch, giving you access to matching segment information.

Other Types of DNA

John provided additional information that may prove to be VERY useful. Both Y-DNA and mitochondrial DNA can be tested as well and may prove to be more useful than autosomal to positively identify the origins of those two specific lines.

Let’s assume that John takes an autosomal test and discovers that indeed, the 3/16th Native estimate was close. 3/16th equates to about 18% Native which would mean that three of his 16 great-great-grandparents were Native.

John told us that his Grandmother Jones was supposed to be 100% Native.

At the great-great-grandparent level, John has 16 ancestors, so eight on his mother’s side, four from maternal grandmother Jones and four from his maternal grandfather Davis.

John carries the mitochondrial DNA of his mother (red boxes and arrows,) and her mother, through a direct line of females back in time. John also carries the Y-DNA of his father (dark blue box, at left above, and blue arrows below.)

Unlike autosomal DNA which is admixed in every generation, mitochondrial DNA (red arrows) is inherited from that direct matrilineal line ONLY and never combines with the DNA of the father. Mothers give their mitochondrial DNA to both sexes of their children, but men never contribute their mitochondrial DNA to offspring. Everyone has their mother’s mitochondrial DNA.

Because it never recombines with DNA from the father, so is never “watered down,” we can “see” much further back in time, even though we can’t yet identify those ancestors.

However, more importantly, in this situation, John can test his own mitochondrial DNA that he inherited from his mother, who inherited it from her mother, to view her direct matrilineal line.

John’s mitochondrial DNA haplogroup that will be assigned during testing tells us unquestionably whether or not his direct matrilineal ancestor was Native on her mother’s line, or not. If not, it may well tell us where that specific line originated.

You can view the countries around the world where Y-DNA haplogroups are found, here, and mitochondrial haplogroups, here.

If John’s mitochondrial DNA haplogroup is Native, that confirms that one specific line is Native. If he can find other testers in his various lines to test either their Y-DNA or mitochondrial DNA, John can determine if other ancestors were Native too. If not, those tests will reveal the origins of that line, separate from the rest of his genealogical lines.

Although John didn’t mention his father’s line, if he takes a Y-DNA test, especially at the Big Y-700 level, that will also reveal the origins of his direct paternal line. Y-DNA doesn’t combine with the other parent’s DNA either, so it reaches far back in time too.

Y-DNA and mitochondrial DNA tests are laser-focused on one line each, and only one line. You don’t have to try to sort it out of the ethnicity “pot,” wondering which ancestor was or was not Native.

My Recommendation

When putting together a testing strategy, I recommend taking advantage of free uploads and inexpensive unlocks when possible.

  • To confirm Native American ancestry via ethnicity testing, I recommend testing at 23andMe and uploading to FamilyTreeDNA, then purchasing the $19 unlock. The free upload and $19 unlock are less expensive than testing there directly.
  • For matching, I recommend testing at Ancestry and uploading to MyHeritage, then unlocking the MyHeritage advanced features for $29, which is less expensive than retesting. Ancestry does not provide segment information, but MyHeritage (and the others) do.

At this point, John will have taken two DNA tests, but is now in all four databases, plus GEDmatch if he uploads there.

  • For genealogy research on John’s lines to determine whether or not his mother’s lines were Native, I recommend an Ancestry and a MyHeritage records subscription, plus using WikiTree, which is free.
  • To determine if John’s mother’s direct matrilineal female line was Native, I recommend that John order the mitochondrial DNA test at FamilyTreeDNA.
  • When ordering multiple tests, or uploading at FamilyTreeDNA, be sure to upload/order all of one person’s tests on the same DNA kit so that those results can be used in combination with each other.

Both males and females can take autosomal and mitochondrial DNA tests.

  • To discover what he doesn’t know about his direct paternal, meaning John’s surname line – I recommend the Big Y-700 test at FamilyTreeDNA.

Only males can take a Y-DNA test, so women would need to ask their father, brother, or paternal uncle, for example, to test their direct paternal line.

  • If John can find a male Davis from his mother’s line, I recommend that he purchase the Big Y-700 test at FamilyTreeDNA for that person, or check to see if someone from his Davis line may have already tested by viewing the Davis DNA Project. Like with mitochondrial DNA, the Y-DNA haplogroup will tell John the origins of his direct Davis male ancestor – plus matching of course. He will be able to determine if they were Native, and if not, discover the origins of the Davis line.
  • For assigning segments to ancestors and triangulating to confirm descent from a common ancestor, I recommend 23andMe, MyHeritage, FamilyTreeDNA and GEDmatch, paired with DNAPainter as a tool.

Shopping and Research List

Here are the tests and links recommended above:

More Than He Asked

I realize this answer is way more than John expected or even knew to ask. That’s because there is often no “one” or “one best” answer. There are many ways to approach the question after the goal is defined, and the first “answer” received may be a bit out of context.

For example, let’s say John has 2% Native ancestry and took a test at a vendor who didn’t detect it. John would believe he had none. But a different vendor might find that 2%. If it’s on his mother’s direct matrilineal line, mitochondrial DNA testing will confirm, or refute Native, beyond any doubt, regardless of autosomal ethnicity results – but only for that specific ancestral line.

Autosomal DNA can suggest Native across all your DNA, but Y-DNA and mitochondrial DNA confirm it for each individual ancestor.

Even when autosomal testing does NOT show Native American, or African, for example, it’s certainly possible that it’s just too far back in time or has not been passed down during random recombination, but either Y-DNA or mitochondrial DNA will unquestionably confirm (or refute) the ancestry in question if the right person is tested.

This is exactly why I attempt to find a cousin who descends appropriately from every ancestor and provide testing scholarships. It’s important to obtain Y-DNA and mitochondrial DNA information for each ancestor.

Which Test Should I Order?

What steps will help you decide which test or tests to take?

  1. Define your testing goal.
  2. Determine if your Y-DNA or mitochondrial DNA will help answer the question.
  3. Determine if you need to find ancestors another generation or two back in time to get the most benefit from DNA testing. In our example, if John discovered that both of his grandparents were enrolled tribal members, that’s huge, and the tribe might have additional information about his family.
  4. Subscribe to Ancestry and MyHeritage records collections as appropriate to perform genealogical research. Additional information not only provides context for your family, it also provides you with the ability to confirm or better understand your ethnicity results.
  5. Extend your tree so that you can obtain the best results from the three vendors who support trees; Ancestry, FamilyTreeDNA, and MyHeritage. All three use trees combined with DNA tests to provide you with additional information.
  6. Order 23andMe and Ancestry autosomal DNA tests.
  7. Either test at or upload one of those tests to MyHeritage, FamilyTreeDNA, and GEDmatch.
  8. If a male, order the Big Y-700 DNA test. Or, find a male from your ancestral line who has taken or will take that test. I always offer a testing scholarship and, of course, share the exciting results!
  9. Order a mitochondrial DNA test for yourself and for appropriately descended family members to represent other ancestors. Remember that your father (and his siblings) all carry your paternal grandmother’s mitochondrial DNA. That’s often a good place to start after testing your own DNA.
  10. If your parents or grandparents are alive, or aunts and uncles, test their autosomal DNA too. They are (at least) one generation closer to your ancestors than you are and will carry more of your ancestors’ DNA.
  11. Your siblings will carry some of your ancestors’ DNA that you do not, so test them too if both of your parents aren’t available for testing.

Enjoy!!!

The Best of 2022

It’s that time of year where we look both backward and forward.

Thank you for your continued readership! Another year under our belts!

I always find it interesting to review the articles you found most interesting this past year.

In total, I published 97 articles in 2022, of which 56 were directly instructional about genetic genealogy. I say “directly instructional,” because, as you know, the 52 Ancestors series of articles are instructional too, but told through the lives of my ancestors. That leaves 41 articles that were either 52 Ancestors articles, or general in nature.

It has been quite a year.

2022 Highlights

In a way, writing these articles serves as a journal for the genetic genealogy community. I never realized that until I began scanning titles a year at a time.

Highlights of 2022 include:

Which articles were your favorites that were published in 2022, and why?

Your Favorites

Often, the topics I select for articles are directly related to your comments, questions and suggestions, especially if I haven’t covered the topic previously, or it needs to be featured again. Things change in this industry, often. That’s a good thing!

However, some articles become forever favorites. Current articles don’t have enough time to amass the number of views accumulated over years for articles published earlier, so recently published articles are often NOT found in the all-time favorites list.

Based on views, what are my readers’ favorites and what do they find most useful?

In the chart below, the 2022 ranking is not just the ranking of articles published in 2022, but the ranking of all articles based on 2022 views alone. Not surprisingly, six of the 15 favorite 2022 articles were published in 2022.

The All-Time Ranking is the ranking for those 2022 favorites IF they fell within the top 15 in the forever ranking, over the entire decade+ that this blog has existed.

2023 Suggestions

I have a few articles already in the works for 2023, including some surprises. I’ll unveil one very soon.

We will be starting out with:

  • Information about RootsTech where I’ll be giving at least 7 presentations, in person, and probably doing a book signing too. Yes, I know, 7 sessions – what was I thinking? I’ve just missed everyone so very much.
  • An article about how accurately Ancestry’s ThruLines predicts Potential Ancestors and a few ways to prove, or disprove, accuracy.
  • The continuation of the “In Search Of” series.

As always, I’m open for 2023 suggestions.

In the comments, let me know what topics you’d like to see.

DNA: In Search of…Full and Half-Siblings

This is the fifth article in our series of articles about searching for unknown close family members, specifically; parents, grandparents, or siblings. However, these same techniques can be applied by genealogists to identify ancestors further back in time as well.

Please note that if a family member has tested and you do NOT see their results, ask them to verify that they have chosen to allow matching and for other people to view them in their match list. That process varies at different vendors.

You can also ask if they can see you in their results.

All Parties Need to Test

Searching for unknown siblings isn’t exactly searching, because to find them, they, themselves, or their descendant(s) must have taken a DNA test at the same vendor where you tested or uploaded a DNA file.

You may know through any variety of methods that they exist, or might exist, but if they don’t take a DNA test, you can’t find them using DNA. This might sound obvious, but I see people commenting and not realizing that the other sibling(s) must test too – and they may not have.

My first questions when someone comments in this vein are:

  1. Whether or not they are positive their sibling actually tested, meaning actually sent the test in to the vendor, and it was received by the testing company. You’d be surprised how many tests are living in permanent residence on someone’s countertop until it gets pushed into the drawer and forgotten about.
  2. If the person has confirmed that their sibling has results posted. They may have returned their test, but the results aren’t ready yet or there was a problem.
  3. AND that both people have authorized matching and sharing of results. Don’t hesitate to reach out to your vendor’s customer care if you need help with this.

Sibling Scenarios

The most common sibling scenarios are when one of two things happens:

  • A known sibling tests, only to discover that they don’t match you in the full sibling range, or not at all, when you expected they would
  • You discover a surprise match in the full or half-sibling range

Let’s talk about these scenarios and how to determine:

  • If someone is a sibling
  • If they are a full or half-sibling
  • If a half-sibling, if they descend from your mother or father

As with everything else genetic, we’ll be gathering and analyzing different pieces of evidence along the way.

Full and Half-Siblings

Just to make sure we are all on the same page:

  • A full sibling is someone who shares both parents with you.
  • A half-sibling is someone who shares one parent with you, but not the other parent.
  • A step-sibling is someone who shares no biological parents with you. This situation occurs when your parent marries their parent, after you are both born, and their parent becomes your step-parent. You share neither of your biological parents with a step-sibling, so you share no DNA and will not show up on each other’s match lists.
  • A three-quarters sibling is someone with whom you share one parent, but two siblings are the other parent. For example, you share the same mother, but one brother fathered you, and your father’s brother fathered your sibling. Yes, this can get very messy and is almost impossible for a non-professional to sort through, if even then. (This is not a solicitation. I do not take private clients.) We will not be addressing this situation specifically.

Caution

With any search for unknown relatives, you have no way of knowing what you will find.

In one’s mind, there are happy reunions, but you may experience something entirely different. Humans are human. Their stories are not always happy or rosy. They may have made mistakes they regret. Or they may have no regrets about anything.

Your sibling may not know about you or the situation under which you, or they, were born. Some women were victims of assault and violence, which is both humiliating and embarrassing. I wrote about difficult situations, here.

Your sibling or close family member may not be receptive to either you, your message, or even your existence. Just be prepared, because the seeking journey may not be pain-free for you or others, and may not culminate with or include happy reunions.

On the other hand, it may.

Please step back and ponder a bit about the journey you are about to undertake and the possible people that may be affected, and how. This box, once opened, cannot be closed again. Be sure you are prepared.

On the other hand, sometimes that box lid pops off, and the information simply falls in your lap one day when you open your match list, and you find yourself sitting there, in shock, staring at a match, trying to figure out what it all means.

Congratulations, You Have a Sibling!

This might not be exactly what runs through your mind when you see that you have a very close match that you weren’t expecting.

The first two things I recommend when making this sort of discovery, after a few deep breaths, a walk, and a cup of tea, are:

  • Viewing what the vendor says
  • Using the DNAPainter Shared cM Relationship Chart

Let’s start with DNAPainter.

DNAPainter

DNAPainter provides a relationship chart, here, based on the values from the Shared cM Project.

You can either enter a cM amount or a percentage of shared DNA. I prefer the cM amount, but it doesn’t really matter.

I’ll enter 2241 cM from a known half-sibling match. To enter a percent, click on the green “enter %.”

As you can see, statistically speaking, this person is slightly more likely to be a half-sibling than they are to be a full sibling. In reality, they could be either.

Looking at the chart below, DNAPainter highlights the possible relationships from the perspective of “Self.”

The average of all the self-reported relationships is shown, on top, so 2613 for a full sibling. The range is shown below, so 1613-3488 for a full sibling.

In this case, there are several possibilities for two people who share 2241 cM of DNA.

I happen to know that these two people are half-siblings, but if I didn’t, it would be impossible to tell from this information alone.

The cM range for full siblings is 1613-3488, and the cM range for half-siblings is 1160-2436.

  • The lower part of the matching range, from 1160-1613 cM is only found in half-siblings.
  • The portion of the range from 1613-2436 cM can be either half or full siblings.
  • The upper part of the range, from 2436-3488 cM is only found in full siblings.

If your results fall into the center portion of the range, you’re going to need to utilize other tools. Fortunately, we have several.

If you’ve discovered something unexpected, you’ll want to verify using these tools, regardless. Use every tool available. Ranges are not foolproof, and the upper and lower 10% of the responses were removed as outliers. You can read more about the shared cM Project, here and here.

Furthermore, people may be reporting some half-sibling relationships as full sibling relationships, because they don’t expect to be half-siblings, so the ranges may be somewhat “off.”

Relationship Probability Calculator

Third-party matching database, GEDmatch, provides a Relationship Probability Calculator tool that is based on statistical probability methods without compiled user input. Both tools are free, and while I haven’t compared every value, both seem to be reasonably accurate, although they do vary somewhat, especially at the outer ends of the ranges.

When dealing with sibling matches, if you are in all four databases, GEDmatch is a secondary resource, but I will include GEDmatch when they have a unique tool as well as in the summary table. Some of your matches may be willing to upload to GEDmatch if the vendor where you match doesn’t provide everything you need and GEDmatch has a supplemental offering.

Next, let’s look at what the vendors say about sibling matches.

Vendors

Each of the major vendors reports sibling relationships in a slightly different way.

Sibling Matches at Ancestry

Ancestry reports sibling relationships as Sister or Brother, but they don’t say half or full.

If you click on the cM portion of the link, you’ll see additional detail, below

Ancestry tells you that the possible relationships are 100% “Sibling.” The only way to discern the difference between full and half is by what’s next.

If the ONLY relationship shown is Sibling at 100%, that can be interpreted to mean this person is a full sibling, and that a half-sibling or other relationship is NOT a possibility.

Ancestry never stipulates full or half.

The following relationship is a half-sibling at Ancestry.

Ancestry identifies that possible range of relationships as “Close Family to First Cousin” because of the overlaps we saw in the DNAPainter chart.

Clicking through shows that there is a range of possible relationships, and Ancestry is 100% sure the relationship is one of those.

DNAPainter agrees with Ancestry except includes the full-sibling relationship as a possibility for 1826 cM.

Sibling Matches at 23andMe

23andMe does identify full versus half-siblings.

DNAPainter disagrees with 23andMe and claims that anyone who shares 46.2% of their DNA is a parent/child.

However, look at the fine print. 23andMe counts differently than any of the other vendors, and DNAPainter relies on the Shared cM Project, which relies on testers entering known relationship matching information. Therefore, at any other vendor, DNAPainter is probably exactly right.

Before we understand how 23andMe counts, we need to understand about half versus fully identical segments.

To determine half or full siblings, 23andMe compares two things:

  1. The amount of shared matching DNA between two people
  2. Fully Identical Regions (FIR) of DNA compared to Half Identical Regions (HIR) of DNA to determine if any of your DNA is fully identical, meaning some pieces of you and your sibling’s DNA is exactly the same on both your maternal and paternal chromosomes.

Here’s an example on any chromosome – I’ve randomly selected chromosome 12. Which chromosome doesn’t matter, except for the X, which is different.

Your match isn’t broken out by maternal and paternal sides. You would simply see, on the chromosome browser, that you and your sibling match at these locations, above.

In reality, though, you have two copies of each chromosome, one from Mom and one from Dad, and so does your sibling.

In this example, Mom’s chromosome is visualized on top, and Dad’s is on the bottom, below, but as a tester, you don’t know that. All you know is that you match your sibling on all of those blue areas, above.

However, what’s actually happening in this example is that you are matching your sibling on parts of your mother’s chromosome and parts of your father’s chromosome, shown above as green areas

23andMe looks at both copies of your chromosome, the one you inherited from Mom, on top, and Dad, on the bottom, to see if you match your sibling on BOTH your mother’s and your father’s chromosomes in that location.

I’ve boxed the green matching areas in purple where you match your sibling fully, on both parents’ chromosomes.

If you and your sibling share both parents, you will share significant amounts of the same DNA on both copies of the same chromosomes, meaning maternal and paternal. In other words, full siblings share some purple fully identical regions (FIR) of DNA with each other, while half-siblings do not (unless they are also otherwise related) because half-siblings only share one parent with each other. Their DNA can’t be fully identical because they have a different parent that contributed the other copy of their chromosome.

Total Shared DNA Fully Identical DNA from Both Parents
Full Siblings ~50% ~25%
Half Siblings ~25% 0
  • Full siblings are expected to share about 50% of the same DNA. In other words, their DNA will match at that location. That’s all the green boxed locations, above.
  • Full siblings are expected to share about 25% of the same DNA from BOTH parents at the same location on BOTH copies of their chromosomes. These are fully identical regions and are boxed in purple, above.

You’ll find fully identical segments about 25% of the time in full siblings, but you won’t find fully identical segments in half-siblings. Please note that there are exceptions for ¾ siblings and endogamous populations.

You can view each match at 23andMe to see if you have any completely identical regions, shown in dark purple in the top comparison of full siblings. Half siblings are shown in the second example, with less total matching DNA and no FIR or completely identical regions.

Please note that your matching amount of DNA will probably be higher at 23andMe than at other companies because:

  • 23andMe includes the X chromosome in the match totals
  • 23andMe counts fully identical matching regions twice. For full siblings, that’s an additional 25%

Therefore, a full sibling with an X match will have a higher total cM at 23andMe than the same siblings elsewhere because not only is the X added into the total, the FIR match region is added a second time too.

Fully Identical Regions (FIR) and Half Identical Regions (HIR) at GEDmatch

At GEDMatch, you can compare two people to each other, with an option to display the matching information and a painted graphic for each chromosome that includes FIR and HIR.

If you need to know if you and a match share fully identical regions and you haven’t tested at 23andMe, you can both upload your DNA data file to GEDmatch and use their One to One Autosomal DNA Comparison.

On the following page, simply enter both kit numbers and accept the defaults, making sure you have selected one of the graphics options.

While GEDmatch doesn’t specifically tell you whether someone is a full or half sibling, you can garner additional information about the relationship based on the graphic at GEDmatch.

GEDMatch shows both half and fully identical regions.

The above match is between two full siblings using a 7 cM threshold. The blue on the bottom bar indicates a match of 7 cM or larger. Black means no match.

The green regions in the top bar indicate places where these two people carry the same DNA on both copies of their chromosome 1. This means that both people inherited the same DNA from BOTH parents on the green segments.

In the yellow regions, the siblings inherited the same DNA from ONE parent, but different DNA in that region from the other parent. They do match each other, just on one of their chromosomes, not both.

Without a tool like this to differentiate between HIR and FIR, you can’t tell if you’re matching someone on one copy of your chromosome, or on both copies.

In the areas marked with red on top, which corresponds to the black on the bottom band, these two siblings don’t match each other because they inherited different DNA from both parents in that region. The yellow in that region is too scattered to be significant.

Full siblings generally share a significant amount of FIR, or fully identical regions of DNA – about 25%.

Half siblings will share NO significant amount of FIR, although some will be FIR on very small, scattered green segments simply by chance, as you can see in the example, below.

This half-sibling match shares no segments large enough to be a match (7 cM) in the black section. In the blue matching section, only a few small green fragments of DNA match fully, which, based on the rest of that matching segment, must be identical by chance or misreads. There are no significant contiguous segments of fully identical DNA.

When dealing with full or half-siblings, you’re not interested in small, scattered segments of fully identical regions, like those green snippets on chromosome 6, but in large contiguous sections of matching DNA like the chromosome 1 example.

GEDmatch can help when you match when a vendor does not provide FIR/HIR information, and you need additional assistance.

Next, let’s look at full and half-siblings at FamilyTreeDNA

Sibling Matches at FamilyTreeDNA

FamilyTreeDNA does identify full siblings.

Relationships other than full siblings are indicated by a range. The two individuals below are both half-sibling matches to the tester.

The full range when mousing over the relationship ranges is shown below.

DNAPainter agrees except also gives full siblings as an option for the two half-siblings.

FamilyTreeDNA also tells you if you have an X match and the size of your X match.

We will talk about X matching in a minute, which, when dealing with sibling identification, can turn out to be very important.

Sibling Matches at MyHeritage

MyHeritage indicates brother or sister for full siblings

MyHeritage provides other “Estimated relationships” for matches too small to be full siblings.

DNAPainter’s chart agrees with this classification, except adds additional relationship possibilities.

Be sure to review all of the information provided by each vendor for close relationships.

View Close Known Relationships

The next easiest step to take is to compare your full or half-sibling match to known close family members from your maternal and paternal sides, respectively. The closer the family members, the better.

It’s often not possible to determine if someone is a half sibling or a full sibling by centiMorgans (cMs) alone, especially if you’re searching for unknown family members.

Let’s start with the simplest situation first.

Let’s say both of your parents have tested, and of course, you match both of them as parents.

Your new “very close match” is in the sibling range.

The first thing to do at each vendor is to utilize that vendor’s shared matches tool and see whether your new match matches one parent, or both.

Here’s an example.

Close Relationships at FamilyTreeDNA

This person has a full sibling match, but let’s say they don’t know who this is and wants to see if their new sibling matches one or both of their parents.

Select the match by checking the box to the left of the match name, then click on the little two-person icon at far right, which shows “In Common” matches

You can see on the resulting shared match list that both of the tester’s parents are shown on the shared match list.

Now let’s make this a little more difficult.

No Parents, No Problem

Let’s say neither of your parents has tested.

If you know who your family is and can identify your matches, you can see if the sibling you match matches other close relatives on both or either side of your family.

You’ll want to view shared matches with your closest known match on both sides of your tree, beginning with the closest first. Aunts, uncles, first cousins, etc.

You will match all of your family members through second cousins, and 90% of your third cousins. You can view additional relationship percentages in the article, How Much of Them is in You?.

I recommend, for this matching purpose, to utilize 2nd cousins and closer. That way you know for sure if you don’t share them as a match with your sibling, it’s because the sibling is not related on that side of the family, not because they simply don’t share any DNA due to their distance.

In this example, you have three sibling matches. Based on your and their matches to the same known first and second cousins, you can see that:

  • Sibling 1 is your full sibling, because you both match the same maternal and paternal first and second cousins
  • Sibling 2 is your paternal half-sibling because you both match paternal second cousins and closer, but not maternal cousins.
  • Sibling 3 is your maternal half-sibling because you both match maternal second cousins and closer, but not paternal cousins.

Close Relationships at Ancestry

Neither of my parents have tested, but my first cousin on my mother’s side has. Let’s say I have a suspected sibling or half-sibling match, so I click on the match’s name, then on Shared Matches.

Sure enough, my new match also matches my first cousin that I’ve labeled as “on my mother’s side.”

If my new match in the sibling range also matches my second cousins or closer on my father’s side, the new match is a full sibling, not a half-sibling.

Close Relationships at MyHeritage

Comparing my closest match provided a real surprise. I wonder if I’ve found a half-sibling to my mother.

Now, THIS is interesting.

Hmmm. More research is needed, beginning with the age of my match. MyHeritage provides ages if the MyHeritage member authorizes that information to be shared.

Close Relationships at 23andMe

Under DNA Relatives, click on your suspected sibling match, then scroll down and select “Find Relatives in Common.”

The Relatives in Common list shows people that match both of you.

The first common match is very close and a similar relationship to my closest match on my father’s side. This would be expected of a sibling. I have no common matches with this match to anyone on my mother’s side, so they are only related on my father’s side. Therefore they are a paternal half-sibling, not a full sibling.

More Tools Are Available

Hopefully, by now, you’ve been able to determine if your mystery match is a sibling, and if so, if they are a half or full sibling, and through which parent.

We have some additional tools that are relevant and can be very informative in some circumstances. I suggest utilizing these tools, even if you think you know the answer.

In this type of situation, there’s no such thing as too much information.

X Matching

X matching, or lack thereof, may help you determine how you are related to someone.

There are two types of autosomal DNA. The X chromosome versus chromosomes 1-22. The X chromosome (number 23) has a unique inheritance path that distinguishes it from your other chromosomes.

The X chromosome inheritance path also differs between men and women.

Here’s my pedigree chart in fan form, highlighting the ancestors who may have contributed a portion of their X chromosome to me. In the closest generation, this shows that I inherited an X chromosome from both of my parents, and who in each of their lines could have contributed an X to them.

The white or uncolored positions, meaning ancestors, cannot contribute any portion of an X chromosome to me based on how the X chromosome is inherited.

You’ll notice that my father inherited none of his X chromosome from any of his paternal ancestors, so of course, I can’t inherit what he didn’t inherit. There are a very limited number of ancestors on my father’s side whom I can inherit any portion of an X chromosome from.

Men receive their Y chromosome from their fathers, so men ONLY receive an X chromosome from their mother.

Therefore, men MUST pass their mother’s X chromosome on to their female offspring because they don’t have any other copy of the X chromosome to pass on.

Men pass no X chromosome to sons.

We don’t need to worry about a full fan chart when dealing with siblings and half-siblings.

We only need to be concerned with the testers plus one generation (parents) when utilizing the X chromosome in sibling situations.

These two female Disney Princesses, above, are full siblings, and both inherited an X chromosome from BOTH their mother and father. However, their father only has one X (red) chromosome to give them, so the two females MUST match on the entire red X chromosome from their father.

Their mother has two X chromosomes, green and black, to contribute – one from each of her parents.

The full siblings, Melody, and Cinderella:

  • May have inherited some portion of the same green and black X chromosomes from their mother, so they are partial matches on their mother’s X chromosome.
  • May have inherited the exact same full X chromosome from their mother (both inherited the entire green or both inherited the entire black), so they match fully on their mother’s X chromosome.
  • May have inherited the opposite X from different maternal grandparents. One inherited the entire green X and one inherited the entire black X, so they don’t match on their mother’s X chromosome.

Now, let’s look at Cinderella, who matches Henry.

This female and male full sibling match can’t share an X chromosome on the father’s side, because the male’s father doesn’t contribute an X chromosome to him. The son, Henry, inherited a Y chromosome instead from his father, which is what made them males.

Therefore, if a male and female match on the X chromosome, it MUST be through HIS mother, but could be through either of her parents. In a sibling situation, an X match between a male and female always indicates the mother.

In the example above, the two people share both of their mother’s X chromosomes, so are definitely (at least) maternally related. They could be full siblings, but we can’t determine that by the X chromosome in this situation, with males.

However, if the male matches the female on HER father’s X chromosome, there a different message, example below.

You can see that the male is related to the female on her father’s side, where she inherited the entire magenta X chromosome. The male inherited a portion of the magenta X chromosome from his mother, so these two people do have an X match. However, he matches on his mother’s side, and she matches on her father’s side, so that’s clearly not the same parent.

  • These people CAN NOT be full siblings because they don’t match on HER mother’s side too, which would also be his mother’s side if they were full siblings.
  • They cannot be maternal half-siblings because their X DNA only matches on her father’s side, but they wouldn’t know that unless she knew which side was which based on share matches.
  • They cannot be paternal half-siblings because he does not have an X chromosome from his father.

They could, however, be uncle/aunt-niece/nephew or first cousins on his mother’s side and her father’s side. (Yes, you’re definitely going to have to read this again if you ever need male-female X matching.)

Now, let’s look at X chromosome matching between two males. It’s a lot less complicated and much more succinct.

Neither male has inherited an X chromosome from their father, so if two males DO match on the X, it MUST be through their mother. In terms of siblings, this would mean they share the same mother.

However, there is one slight twist. In the above example, you can see that the men inherited a different proportion of the green and black X chromosomes from their common mother. However, it is possible that the mother could contribute her entire green X chromosome to one son, Justin in this example, and her entire black X chromosome to Henry.

Therefore, even though Henry and Justin DO share a mother, their X chromosome would NOT match in this scenario. This is rare but does occasionally happen.

Based on the above examples, the X chromosome may be relevant in the identification of full or half siblings based on the sexes of the two people who otherwise match at a level indicating a full or half-sibling relationship.

Here’s a summary chart for sibling X matching.

X Match Female Male
Female Will match on shared father’s full X chromosome, mother’s X is the same rules as chromosomes 1-22 Match through male’s mother, but either of female’s parents. If the X match is not through the female’s mother, they are not full siblings nor maternal half-siblings. They cannot have an X match through the male’s father. They are either full or half-siblings through their mother if they match on both of their mother’s side. If they match on his mother’s side, and her father’s side, they are not siblings but could be otherwise closely related.
Male Match through male’s mother, but either of female’s parents. If the X match is not through the female’s mother, they are not full siblings nor maternal half-siblings. They cannot have an X match through the male’s father. They are either full or half-siblings through their mother if they match on both or their mother’s side. If they match on his mother’s side, and her father’s side, they are not siblings but could be otherwise closely related. Both males are related on their mother’s side – either full or half-siblings.

Here’s the information presented in a different way.

DOES match X summary:

  • If a male DOES match a female on the X, he IS related to her through HIS mother’s side, but could match her on her mother or father’s side. If their match is not through her mother, then they are not full siblings nor maternal half-siblings. They cannot match through his father, so they cannot be paternal half-siblings.
  • If a female DOES match a female on the X, they could be related on either side and could be full or half-siblings.
  • If a male DOES match a male on the X, they ARE both related through their mother. They may also be related on their father’s side, but the X does not inform us of that.

Does NOT match X summary:

  • If a male does NOT match a female on the X, they are NOT related through HIS mother and are neither full siblings nor maternal half-siblings. Since a male does not have an X chromosome from his father, they cannot be paternal half-siblings based on an X match.
  • If a male does NOT match a male, they do NOT share a mother.
  • If a female does NOT match another female on the X, they are NOT full siblings and are NOT half-siblings on their paternal side. Their father only has one X chromosome, and he would have given the same X to both daughters.

Of the four autosomal vendors, only 23andMe and FamilyTreeDNA report X chromosome results and matching, although the other two vendors, MyHeritage and Ancestry, include the X in their DNA download file so you can find X matches with those files at either FamilyTreeDNA or GEDMatch if your match has or will upload their file to either of those vendors. I wrote step-by-step detailed download/upload instructions, here.

X Matching at FamilyTreeDNA

In this example from FamilyTreeDNA, the female tester has discovered two half-sibling matches, both through her father. In the first scenario, she matches a female on the full X chromosome (181 cM). She and her half-sibling MUST share their father’s entire X chromosome because he only had one X, from his mother, to contribute to both of his daughters.

In the second match to a male half-sibling, our female tester shares NO X match because her father did not contribute an X chromosome to his son.

If we didn’t know which parents these half-sibling matches were through, we can infer from the X matching alone that the male is probably NOT through the mother.

Then by comparing shared matches with each sibling, Advanced Matches, or viewing the match Matrix, we can determine if the siblings match each other and are from the same or different sides of the family.

Under Additional Tests and Tools, Advanced Matching, FamilyTreeDNA provides an additional tool that can show only X matches combined with relationships.

Of course, you’ll need to view shared matches to see which people match the mother and/or match the father.

To see who matches each other, you’ll need to use the Matrix tool.

At FamilyTreeDNA, the Matrix, located under Autosomal DNA Results and Tools, allows you to select your matches to see if they also match each other. If you have known half-siblings, or close relatives, this is another way to view relationships.

Here’s an example using my father and two paternal half-siblings. We can see that the half-siblings also match each other, so they are (at least) half-siblings on the paternal side too.

If they also matched my mother, we would be full siblings, of course.

Next, let’s use Y DNA and mitochondrial DNA.

Y DNA and Mitochondrial DNA

In addition to autosomal DNA, we can utilize Y DNA and mitochondrial DNA (mtDNA) in some cases to identify siblings or to narrow or eliminate relationship possibilities.

Given that Y DNA and mitochondrial DNA both have distinctive inheritance paths, full and half-siblings will, or will not, match under various circumstances.

Y DNA

Y DNA is passed intact from father to son, meaning it’s not admixed with any of the mother’s DNA. Daughters do not inherit Y DNA from their father, so Y DNA is only useful for male-to-male comparisons.

Two types of Y DNA are used for genealogy, STR markers for matching, and haplogroups, and both are equally powerful in slightly different ways.

Y DNA at FamilyTreeDNA

Men can order either 37 or 111 STR marker tests, or the BIg Y which provides more than 700 markers and more. FamilyTreeDNA is the only one of the vendors to offer Y DNA testing that includes STR markers and matching between men.

Men who order these tests will be compared for matching on either 37, 111 or 700 STR markers in addition to SNP markers used for haplogroup identification and assignment.

Fathers will certainly match their sons, and paternal line brothers will match each other, but they will also match people more distantly related.

However, if two men are NOT either full or half siblings on the paternal side, they won’t match at 111 markers.

If two men DON’T match, especially at high marker levels, they likely aren’t siblings. The word “likely” is in there because, very occasionally, a large deletion occurs that prevents STR matching, especially at lower levels.

Additionally, men who take the 37 or 111 marker test also receive an estimated haplogroup at a high level for free, without any additional testing.

However, if men take the Big Y-700 test, they not only will (or won’t) match on up to 700 STR markers, they will also receive a VERY refined haplogroup via SNP marker testing that is often even more sensitive in terms of matching than STR markers. Between these two types of markers, Y DNA testing can place men very granularly in relation to other men.

Men can match in two ways on Y DNA, and the results are very enlightening.

If two men match on BOTH their most refined haplogroup (Big Y test) AND STR markers, they could certainly be siblings or father/son. They could also be related on the same line for another reason, such as known or unknown cousins or closer relationships like uncle/nephew. Of course, Y DNA, in addition to autosomal matching, is a powerful combination.

Conversely, if two men don’t have a similar or close haplogroup, they are not a father and son or paternal line siblings.

FamilyTreeDNA offers both inexpensive entry-level testing (37 and 111 markers) and highly refined advanced testing of most of the Y chromosome (Big Y-700), so haplogroup assignments can vary widely based on the test you take. This makes haplogroup matching and interpretation a bit more complex.

For example, haplogroups R-M269 and I-BY14000 are not related in thousands of years. One is haplogroup R, and one is haplogroup I – completely different branches of the Y DNA tree. These two men won’t match on STR markers or their haplogroup.

However, because FamilyTreeDNA provides over 50,000 different haplogroups, or tree branches, for Big Y testers, and they provide VERY granular matching, two father/son or sibling males who have BOTH tested at the Big Y-700 level will have either the exact same haplogroup, or at most, one branch difference on the tree if a mutation occurred between father and son.

If both men have NOT tested at the Big Y-700 level, their haplogroups will be on the same branch. For example, a man who has only taken a 37/111 marker STR test may be estimated at R-M269, which is certainly accurate as far as it goes.

His sibling who has taken a Big Y test will be many branches further downstream on the tree – but on the same large haplogroup R-M269 branch. It’s essential to pay attention to which tests a Y DNA match has taken when analyzing the match.

The beauty of the two kinds of tests is that even if one haplogroup is very general due to no Big Y test, their STR markers should still match. It’s just that sometimes this means that one hand is tied behind your back.

Y DNA matching alone can eliminate the possibility of a direct paternal line connection, but it cannot prove siblingship or paternity alone – not without additional information.

The Advanced Matching tool will provide a list of matches in all categories selected – in this case, both the 111 markers and the Family Finder test. You can see that one of these men is the father of the tester, and one is the full sibling.

You can view haplogroup assignments on the public Y DNA tree, here. I wrote about using the public tree, here.

In addition, recently, FamilyTreeDNA launched the new Y DNA Discover tool, which explains more about haplogroups, including their ages and other fun facts like migration paths along with notable and ancient connections. I wrote about using the Discover tool, here.

Y DNA at 23andMe

Testers receive a base haplogroup with their autosomal test. 23andMe tests a limited number of Y DNA SNP locations, but they don’t test many, and they don’t test STR markers, so there is no Y DNA matching and no refined haplogroups.

You can view the haplogroups of your matches. If your male sibling match does NOT share the same haplogroup, the two men are not paternal line siblings. If two men DO share the same haplogroup, they MIGHT be paternal siblings. They also might not.

Again, autosomal close matching plus haplogroup comparisons include or exclude paternal side siblings for males.

Paternal side siblings at 23andMe share the same haplogroup, but so do many other people. These two men could be siblings. The haplogroups don’t exclude that possibility. If the haplogroups were different, that would exclude being either full or paternal half-siblings.

Men can also compare their mitochondrial DNA to eliminate a maternal relationship.

These men are not full siblings or maternal half-siblings. We know, unquestionably, because their mitochondrial haplogroups don’t match.

23andMe also constructs a genetic tree, but often struggles with close relative placement, especially when half-relationships are involved. I do not recommend relying on the genetic tree in this circumstance.

Mitochondrial DNA

Mitochondrial DNA is passed from mothers to all of their children, but only females pass it on. If two people, males or females, don’t match on their mitochondrial DNA test, with a couple of possible exceptions, they are NOT full siblings, and they are NOT maternal half-siblings.

Mitochondrial DNA at 23andMe

23andMe provides limited, base mitochondrial haplogroups, but no matching. If two people don’t have the same haplogroup at 23andMe, they aren’t full or maternal siblings, as illustrated above.

Mitochondrial DNA at FamilyTreeDNA

FamilyTreeDNA provides both mitochondrial matching AND a much more refined haplogroup. The full sequence test (mtFull), the only version sold today, is essential for reliable comparisons.

Full siblings or maternal half-siblings will always share the same haplogroup, regardless of their sex.

Generally, a full sibling or maternal half-sibling match will match exactly at the full mitochondrial sequence (FMS) level with a genetic distance of zero, meaning fully matching and no mismatching mutations.

There are rare instances where maternal siblings or even mothers and children do not match exactly, meaning they have a genetic distance of greater than 0, because of a mutation called a heteroplasmy.

I wrote about heteroplasmies, here.

Like Y DNA, mitochondrial DNA cannot identify a sibling or parental relationship without additional evidence, but it can exclude one, and it can also provide much-needed evidence in conjunction with autosomal matching. The great news is that unlike Y DNA, everyone has mitochondrial DNA and it comes directly from their mother.

Once again, FamilyTreeDNA’s Advanced Matching tool provides a list of people who match you on both your mitochondrial DNA test and the Family Finder autosomal test, including transfers/uploads, and provides a relationship.

You can see that our tester matches both a full sibling and their mother. Of course, a parent/child match could mean that our tester is a female and one of her children, of either sex, has tested.

Below is an example of a parent-child match that has experienced a heteroplasmy.

Based on the comparison of both the mitochondrial DNA test, plus the autosomal Family Finder test, you can verify that this is a close family relationship.

You can also eliminate potential relationships based on the mitochondrial DNA inheritance path. The mitochondrial DNA of full siblings and maternal half-siblings will always match at the full sequence and haplogroup level, and paternal half-siblings will never match. If paternal half-siblings do match, it’s happenstance or because of a different reason.

Sibling Summary and Checklist

I’ve created a quick reference checklist for you to use when attempting to determine whether or not a match is a sibling, and, if so, whether they are half or full siblings. Of course, these tools are in addition to the DNAPainter Shared cM Tool and GEDmatch’s Relationship Predictor Calculator.

FamilyTreeDNA Ancestry 23andMe MyHeritage GEDmatch
Matching Yes Yes Yes Yes Yes
Shared Matches Yes – In Common With Yes – Shared Matches Yes – Relatives in Common Yes – Review DNA Match Yes – People who match both or 1 of 2 kits
Relationship Between Shared Matches No No No Yes, under shared match No

Full Siblings Yes Sibling, implies full Yes Brother, Sister, means full No
Half Siblings Sibling, Uncle/Aunt-Niece/Nephew, Grandparent-Grandchild Close Family – 1C Yes Half sibling, aunt/uncle-niece-nephew No
Fully Identical Regions (FIR) No No Yes No Yes
Half Identical Regions (HIR) No No Yes No Yes
X matching Yes No Yes No Yes
Unusual Reporting or Anomalies No No, Timber is not used on close relationships X match added into total, FIR added twice No Matching amount can vary from vendors
Y DNA Yes, STRs, refined haplogroups, matching No High-level haplogroup only, no matching No No, only if tester enters haplogroup manually
Mitochondrial DNA Yes, full sequence, matching, refined haplogroup No High-level haplogroup only, no matching No No, only if tester enters haplogroup manually
Combined Tools (Autosomal, X, Y, mtDNA) Yes No No No No

*Autoclusters through Genetic Affairs show cluster relationships of matches to the tester and to each other, but not all matches are included, including close matches. While this is a great tool, it’s not relevant for determining close and sibling relationships. See the article, AutoClustering by Genetic Affairs, here.

Additional Resources

Some of you may be wondering how endogamy affects sibling numbers.

Endogamy makes almost everything a little more complex. I wrote about endogamy and various ways to determine if you have an endogamous heritage, here.

Please note that half-siblings with high cM matches also fall into the range of full siblings (1613-3488), with or without endogamy. This may be, but is not always, especially pronounced in endogamous groups.

As another resource, I wrote an earlier article, Full or Half Siblings, here, that includes some different examples.

Strategy

You have a lot of quills in your quiver now, and I wish you the best if you’re trying to unravel a siblingship mystery.

You may not know who your biological family is, or maybe your sibling doesn’t know who their family is, but perhaps your close relatives know who their family is and can help. Remember, the situation that has revealed itself may be a shock to everyone involved.

Above all, be kind and take things slow. If your unexpected sibling match becomes frightened or overwhelmed, they may simply check out and either delete their DNA results altogether or block you. They may have that reaction before you have a chance to do anything.

Because of that possibility, I recommend performing your analysis quickly, along with taking relevant screenshots before reaching out so you will at least have that much information to work with, just in case things go belly up.

When you’re ready to make contact, I suggest beginning by sending a friendly, short, message saying that you’ve noticed that you have a close match (don’t say sibling) and asking what they know about their family genealogy – maybe ask who their grandparents are or if they have family living in the area where you live. I recommend including a little bit of information about yourself, such as where you were born and are from.

I also refrain from using the word adoption (or similar) in the beginning or giving too much detailed information, because it sometimes frightens people, especially if they know or discover that there’s a painful or embarrassing family situation.

And, please, never, ever assume the worst of anyone or their motives. They may be sitting at their keyboard with the same shocked look on their face as you – especially if they have, or had, no idea. They may need space and time to reach a place of acceptance. There’s just nothing more emotionally boat-capsizing in your life than discovering intimate and personal details about your parents, one or both, especially if that discovery is disappointing and image-altering.

Or, conversely, your sibling may have been hoping and waiting just for you!

Take a deep breath and let me know how it goes!

DNA: In Search of…Signs of Endogamy

This is the fourth in our series of articles about searching for unknown close family members, specifically; parents, grandparents, or siblings. However, these same techniques can be applied by genealogists to ancestors further back in time as well.

In this article, we discuss endogamy – how to determine if you have it, from what population, and how to follow the road signs.

After introductions, we will be covering the following topics:

  • Pedigree collapse and endogamy
  • Endogamous groups
  • The challenge(s) of endogamy
  • Endogamy and unknown close relatives (parents, grandparents)
  • Ethnicity and Populations
  • Matches
  • AutoClusters
  • Endogamous Relationships
  • Endogamous DNA Segments
  • “Are Your Parents Related?” Tool
  • Surnames
  • Projects
  • Locations
  • Y DNA, Mitochondrial DNA, and Endogamy
  • Endogamy Tools Summary Tables
    • Summary of Endogamy Tools by Vendor
    • Summary of Endogamous Populations Identified by Each Tool
    • Summary of Tools to Assist People Seeking Unknown Parents and Grandparents

What Is Endogamy and Why Does It Matter?

Endogamy occurs when a group or population of people intermarry among themselves for an extended period of time, without the introduction of many or any people from outside of that population.

The effect of this continual intermarriage is that the founders’ DNA simply gets passed around and around, eventually in small segments.

That happens because there is no “other” DNA to draw from within the population. Knowing or determining that you have endogamy helps make sense of DNA matching patterns, and those patterns can lead you to unknown relatives, both close and distant.

This Article

This article serves two purposes.

  • This article is educational and relevant for all researchers. We discuss endogamy using multiple tools and examples from known endogamous people and populations.
  • In order to be able to discern endogamy when we don’t know who our parents or grandparents are, we need to know what signs and signals to look for, and why, which is based on what endogamy looks like in people who know their heritage.

There’s no crystal ball – no definitive “one-way” arrow, but there are a series of indications that suggest endogamy.

Depending on the endogamous population you’re dealing with, those signs aren’t always the same.

If you’re sighing now, I understand – but that’s exactly WHY I wrote this article.

We’re covering a lot of ground, but these road markers are invaluable diagnostic tools.

I’ve previously written about endogamy in the articles:

Let’s start with definitions.

Pedigree Collapse and Endogamy

Pedigree collapse isn’t the same as endogamy. Pedigree collapse is when you have ancestors that repeat in your tree.

In this example, the parents of our DNA tester are first cousins, which means the tester shares great-grandparents on both sides and, of course, the same ancestors from there on back in their tree.

This also means they share more of those ancestors’ DNA than they would normally share.

John Smith and Mary Johnson are both in the tree twice, in the same position as great-grandparents. Normally, Tester Smith would carry approximately 12.5% of each of his great-grandparents’ DNA, assuming for illustration purposes that exactly 50% of each ancestor’s DNA is passed in each generation. In this case, due to pedigree collapse, 25% of Tester Smith’s DNA descends from John Smith, and another 25% descends from Mary Johnson, double what it would normally be. 25% is the amount of DNA contribution normally inherited from grandparents, not great-grandparents.

While we may find first cousin marriages a bit eyebrow-raising today, they were quite common in the past. Both laws and customs varied with the country, time, social norms, and religion.

Pedigree Collapse and Endogamy is NOT the Same

You might think that pedigree collapse and endogamy is one and the same, but there’s a difference. Pedigree collapse can lead to endogamy, but it takes more than one instance of pedigree collapse to morph into endogamy within a population. Population is the key word for endogamy.

The main difference is that pedigree collapse occurs with known ancestors in more recent generations for one person, while endogamy is longer-term and systemic in a group of people.

Picture a group of people, all descended from Tester Smith’s great-grandparents intermarrying. Now you have the beginnings of endogamy. A couple hundred or a few hundred years later, you have true endogamy.

In other words, endogamy is pedigree collapse on a larger scale – think of a village or a church.

My ancestors’ village of Schnait, in Germany, is shown above in 1685. One church and maybe 30 or 40 homes. According to church and other records, the same families had inhabited this village, and region, for generations. It’s a sure bet that both pedigree collapse and endogamy existed in this small community.

If pedigree collapse happens over and over again because there are no other people within the community to marry, then you have endogamy. In other words, with endogamy, you assuredly DO have historical pedigree collapse, generally back in time, often before you can identify those specific ancestors – because everyone descends from the same set of founders.

Endogamy Doesn’t Necessarily Indicate Recent Pedigree Collapse

With deep, historic endogamy, you don’t necessarily have recent pedigree collapse, and in fact, many people do not. Jewish people are a good example of this phenomenon. They shared ancestors for hundreds or thousands of years, depending on which group we are referring to, but in recent, known, generations, many Jewish people aren’t related. Still, their DNA often matches each other.

The good news is that there are telltale signs and signals of endogamy.

The bad news is that not all of these are obvious, meaning as an aid to people seeking clues about unknown close relatives, and other “signs” aren’t what they are believed to be.

Let’s step through each endogamy identifier, or “hint,” and then we will review how we can best utilize this information.

First, let’s take a look at groups that are considered to be endogamous.

Endogamous Groups

Jewish PeopleSpecifically groups that were isolated from other groups of Jewish (and other) people; Ashkenazi (Germany, Northern France, and diaspora), Sephardic (Spanish, Iberia, and diaspora), Mizrahi (Israel, Middle Eastern, and diaspora,) Ethiopian Jews, and possibly Jews from other locations such as Mountain Jews from Kazakhstan and the Caucasus.

AcadiansDescendants of about 60 French families who settled in “Acadia” beginning about 1604, primarily on the island of Nova Scotia, and intermarried among themselves and with the Mi’kmaq people. Expelled by the English in 1755, they were scattered in groups to various diasporic regions where they continued to intermarry and where their descendants are found today. Some Acadians became the Cajuns of Louisiana.

Anabaptist Protestant FaithsAmish, Mennonite, and Brethren (Dunkards) and their offshoots are Protestant religious sects founded in Europe in the 14th, 15th, and 16th centuries on the principle of baptizing only adults or people who are old enough to choose to follow the faith, or rebaptizing people who had been previously baptized as children. These Anabaptist faiths tend to marry within their own group or church and often expel those who marry outside of the faith. Many emigrated to the American colonies and elsewhere, seeking religious freedom. Occasionally those groups would locate in close proximity and intermarry, but not marry outside of other Anabaptist denominations.

Native American (Indigenous) People – all indigenous peoples found in North and South America before European colonization descended from a small number of original founders who probably arrived at multiple times.

Indigenous Pacific Islanders – Including indigenous peoples of Australia, New Zealand, and Hawaii prior to colonization. They are probably equally as endogamous as Native American people, but I don’t have specific examples to share.

Villages – European or other villages with little inflow or whose residents were restricted from leaving over hundreds of years.

Other groups may have significant multiple lines of pedigree collapse and therefore become endogamous over time. Some people from Newfoundland, French Canadians, and Mormons (Church of Jesus Christ of Latter-Day Saints) come to mind.

Endogamy is a process that occurs over time.

Endogamy and Unknown Relatives

If you know who your relatives are, you may already know you’re from an endogamous population, but if you’re searching for close relatives, it’s helpful to be able to determine if you have endogamous heritage, at least in recent generations.

If you know nothing about either parent, some of these tools won’t help you, at least not initially, but others will. However, as you add to your knowledge base, the other tools will become more useful.

If you know the identity of one parent, this process becomes at least somewhat easier.

In future articles, we will search specifically for parents and each of your four grandparents. In this article, I’ll review each of the diagnostic tools and techniques you can use to determine if you have endogamy, and perhaps pinpoint the source.

The Challenge

People with endogamous heritage are related in multiple, unknown ways, over many generations. They may also be related in known ways in recent generations.

If both of your parents share the SAME endogamous culture or group of relatives:

  • You may have significantly more autosomal DNA matches than people without endogamy, unless that group of people is under-sampled. Jewish people have significantly more matches, but Native people have fewer due to under-sampling.
  • You may experience a higher-than-normal cM (centiMorgan) total for estimated relationships, especially more distant relationships, 3C and beyond.
  • You will have many matches related to you on both your maternal and paternal sides.
  • Parts of your autosomal DNA will be the same on both your mother’s and father’s sides, meaning your DNA will be fully identical in some locations. (I’ll explain more in a minute.)

If either (or both) of your parents are from an endogamous population, you:

  • Will, in some cases, carry identifying Y and mitochondrial DNA that points to a specific endogamous group. This is true for Native people, can be true for Jewish people and Pacific Islanders, but is not true for Anabaptist people.

One Size Does NOT Fit All

Please note that there is no “one size fits all.”

Each or any of these tools may provide relevant hints, depending on:

  • Your heritage
  • How many other people have tested from the relevant population group
  • How many close or distant relatives have tested
  • If your parents share the same heritage
  • Your unique DNA inheritance pattern
  • If your parents, individually, were fully endogamous or only partly endogamous, and how far back generationally that endogamy occurred

For example, in my own genealogy, my maternal grandmother’s father was Acadian on his father’s side. While I’m not fully endogamous, I have significantly more matches through that line proportionally than on my other lines.

I have Brethren endogamy on my mother’s side via her paternal grandmother.

Endogamous ancestors are shown with red stars on my mother’s pedigree chart, above. However, please note that her maternal and paternal endogamous ancestors are not from the same endogamous population.

However, I STILL have fewer matches on my mother’s side in total than on my father’s side because my mother has recent Dutch and recent German immigrants which reduces her total number of matches. Neither of those lines have had as much time to produce descendants in the US, and Europe is under-sampled when compared with the US where more people tend to take DNA tests because they are searching for where they came from.

My father’s ancestors have been in the US since it was a British Colony, and I have many more cousins who have tested on his side than mother’s.

If you looked at my pedigree chart and thought to yourself, “that’s messy,” you’d be right.

The “endogamy means more matches” axiom does not hold true for me, comparatively, between my parents – in part because my mother’s German and Dutch lines are such recent immigrants.

The number of matches alone isn’t going to tell this story.

We are going to need to look at several pieces and parts for more information. Let’s start with ethnicity.

Ethnicity and Populations

Ethnicity can be a double-edged sword. It can tell you exactly nothing you couldn’t discern by looking in the mirror, or, conversely, it can be a wealth of information.

Ethnicity reveals the parts of the world where your ancestors originated. When searching for recent ancestors, you’re most interested in majority ethnicity, meaning the 50% of your DNA that you received from each of your parents.

Ethnicity results at each vendor are easy to find and relatively easy to understand.

This individual at FamilyTreeDNA is 100% Ashkenazi Jewish.

If they were 50% Jewish, we could then estimate, and that’s an important word, that either one of their parents was fully Jewish, and not the other, or that two of their grandparents were Jewish, although not necessarily on the same side.

On the other hand, my mother’s ethnicity, shown below, has nothing remarkable that would point to any majority endogamous population, yet she has two.

The only hint of endogamy from ethnicity would be her ~1% Americas, and that isn’t relevant for finding close relatives. However, minority ancestry is very relevant for identifying Native ancestors, which I wrote about, here.

You can correlate or track your ethnicity segments to specific ancestors, which I discussed in the article, Native American & Minority Ancestors Identified Using DNAPainter Plus Ethnicity Segments, here.

Since I wrote that article, FamilyTreeDNA has added the feature of ethnicity or population Chromosome Painting, based on where each of your populations fall on your chromosomes.

In this example on chromosome 1, I have European ancestry (blue,) except for the pink Native segment, which occurs on the following segment in the same location on my mother’s chromosome 1 as well.

Both 23andMe, and FamilyTreeDNA provide chromosome painting AND the associated segment information so you can identify the relevant ancestors.

Ancestry is in the process of rolling out an ethnicity painting feature, BUT, it has no segment or associated matching information. While it’s interesting eye candy, it’s not terribly useful beyond the ethnicity information that Ancestry already provides. However, Jonny Perl at DNAPainter has devised a way to estimate Ancestry’s start and stop locations, here. Way to go Jonny!

Now all you need to do is convince your Ancestry matches to upload their DNA file to one of the three databases, FamilyTreeDNA, MyHeritage, and GEDMatch, that accept transfers, aka uploads. This allows matching with segment data so that you can identify who matches you on that segment, track your ancestors, and paint your ancestral segments at DNAPainter.

I provided step-by-step instructions, here, for downloading your raw DNA file from each vendor in order to upload the file to another vendor.

Ethnicity Sides

Three of the four DNA testing vendors, 23andMe, FamilyTreeDNA, and recently, Ancestry, attempt to phase your ethnicity DNA, meaning to assign it to one parental “side” or the other – both in total and on each chromosome.

Here’s Ancestry’s SideView, where your DNA is estimated to belong to parent 1 and parent 2. I detailed how to determine which side is which, here, and while that article was written specifically pertaining to Ancestry’s SideView, the technique is relevant for all the vendors who attempt to divide your DNA into parents, a technique known as phasing.

I say “attempt” because phasing may or may not be accurate, meaning the top chromosome may not always be parent 1, and the bottom chromosome may not always be chromosome 2.

Here’s an example at 23andMe.

See the two yellow segments. They are both assigned as Native. I happen to know one is from the mother and one is from the father, yet they are both displayed on the “top” chromosome, which one would interpret to be the same parent.

I am absolutely positive this is not the case because this is a close family member, and I have the DNA of the parent who contributed the Native segment on chromosome 1, on the top chromosome. That parent does not have a Native segment on chromosome 2 to contribute. So that Native segment had to be contributed by the other parent, but it’s also shown on the top chromosome.

The DNA segments circled in purple belong together on the same “side” and were contributed to the tester by the same parent. The Native segment on chromosome 2 abuts a purple African segment, suggesting perhaps that the ancestor who contributed that segment was mixed between those ethnicities. In the US, that suggests enslavement.

The other African segments, circled, are shown on the second chromosome in each pair.

To be clear, parent 1 is not assigned by the vendors to either mother or father and will differ by person. Your parent 1, or the parent on the top chromosome may be your mother and another person’s parent 1 may be their father.

As shown in this example, parents can vary by chromosome, a phenomenon known as “strand swap.” Occasionally, the DNA can even be swapped within a chromosome assignment.

You can, however, get an idea of the division of your DNA at any specific location. As shown above, you can only have a maximum of two populations of DNA on any one chromosome location.

In our example above, this person’s majority ancestry is European (blue.) On each chromosome where we find a minority segment, the opposite chromosome in the same location is European, meaning blue.

Let’s look at another example.

At FamilyTreeDNA, the person whose ethnicity painting is shown below has a Native American (pink) ancestor on their father’s side. FamilyTreeDNA has correctly phased or identified their Native segments as all belonging to the second chromosome in each pair.

Looking at chromosome 18, for example, most of their father’s chromosome is Native American (pink). The other parent’s chromosome is European (dark blue) at those same locations.

If one of the parents was of one ethnicity, and the other parent is a completely different ethnicity, then one bar of each chromosome would be all pink, for example, and one would be entirely blue, representing the other ethnicity.

Phasing ethnicity or populations to maternal and paternal sides is not foolproof, and each chromosome is phased individually.

Ethnicity can, in some cases, give you a really good idea of what you’re dealing with in terms of heritage and endogamy.

If someone had an Ashkenazi Jewish father and European mother, for example, one copy of each chromosome would be yellow (Ashkenazi Jewish), and one would be blue (European.)

However, if each of their parents were half European Jewish and half European (not Jewish), then their different colored segments would be scattered across their entire set of chromosomes.

In this case, both of the tester’s parents are mixed – European Jewish (green) and Western Europe (blue.) We know both parents are admixed from the same two populations because in some locations, both parents contributed blue (Western Europe), and in other locations, both contributed Jewish (green) segments.

Both MyHeritage and Ancestry provide a secondary tool that’s connected to ethnicity, but different and generally in more recent times.

Ancestry’s DNA Communities

While your ethnicity may not point to anything terribly exciting in terms of endogamy, Genetic Communities might. Ancestry says that a DNA Community is a group of people who share DNA because their relatives recently lived in the same place at the same time, and that communities are much smaller than ethnicity regions and reach back only about 50-300 years.

Based on the ancestors’ locations in the trees of me and my matches, Ancestry has determined that I’m connected to two communities. In my case, the blue group is clearly my father’s line. The orange group could be either parent, or even a combination of both.

My endogamous Brethren could be showing up in Maryland, Pennsylvania, and Ohio, but it’s uncertain, in part, because my father’s ancestral lines are found in Virginia, West Virginia, and Maryland too.

These aren’t useful for me, but they may be more useful for fully endogamous people, especially in conjunction with ethnicity.

My Acadian cousin’s European ethnicity isn’t informative.

However, viewing his DNA Communities puts his French heritage into perspective, especially combined with his match surnames.

I wrote about DNA Communities when it was introduced with the name Genetic Communities, here.

MyHeritage’s Genetic Groups

MyHeritage also provides a similar feature that shows where my matches’ ancestors lived in the same locations as mine.

One difference, though, is that testers can adjust their ethnicity results confidence level from high, above, to low, below where one of my Genetic Groups overlaps my ethnicity in the Netherlands.

You can also sort your matches by Genetic Groups.

The results show you not only who is in the group, but how many of your matches are in that group too, which provides perspective.

I wrote about Genetic Groups, here.

Next, let’s look at how endogamy affects your matches.

Matches

The number of matches that a person has who is from an entirely endogamous community and a person with no endogamy may be quite different.

FamilyTreeDNA provides a Family Matching feature that triangulates your matches and assigns them to your paternal or maternal side by using known matches that you have linked to their profile cards in your tree. You must link people for the Family Matching feature known as “bucketing” to be enabled.

The people you link are then processed for shared matches on the same chromosome segment(s). Triangulated individuals are then deposited in your maternal, paternal, and both buckets.

Obviously, your two parents are the best people to link, but if they haven’t tested (or uploaded their DNA file from another vendor) and you have other known relatives, link them using the Family Tree tab at the top of your personal page.

I uploaded my Ancestry V4 kit to use as an example for linking. Let’s pretend that’s my sister. If I had not already linked my Ancestry V4 kit to “my sister’s” profile card, I’d want to do that and link other known individuals the same way. Just drag and drop the match to the correct profile card.

Note that a full or half sibling will be listed as such at FamilyTreeDNA, but an identical twin will show as a potential parent/child match to you. You’re much more likely to find a parent than an identical twin, but just be aware.

I’ve created a table of FamilyTreeDNA bucketed match results, by category, comparing the number of matches in endogamous categories with non-endogamous.

Total Matches Maternal Matches Paternal Matches Both % Both % DNA Unassigned
100% Jewish 34,637 11,329 10,416 4,806 13.9 23.3
100% Jewish 32,973 10,700 9,858 4,606 14 23.7
100% Jewish 32,255 9,060 10,970 3,892 12 25.8
75% Jewish 24,232 11,846 Only mother linked Only mother linked Only mother linked
100% Acadian 8093 3826 2299 1062 13 11
100% Acadian 7828 3763 1825 923 11.8 17
Not Endogamous 6760 3845 1909 13 0.19 14.5
Not Endogamous 7723 1470 3317 6 0.08 38
100% Native American 1,115 Unlinked Unlinked Unlinked
100% Native American 885 290 Unknown Can’t calculate without at least one link on both sides

The 100% Jewish, Acadian, and Not Endogamous testers both have linked their parents, so their matches, if valid (meaning not identical by chance, which I discussed here,) will match them plus one or the other parent.

One person is 75% Jewish and has only linked their Jewish mother.

The Native people have not tested their parents, and the first Native person has not linked anyone in their tree. The second Native person has only linked a few maternal matches, but their mother has not tested. They are seeking their father.

It’s very difficult to find people who are fully Native as testers. Furthermore, Native people are under-sampled. If anyone knows of fully Native (or other endogamous) people who have tested and linked their parents or known relatives in their trees, and will allow me to use their total match numbers anonymously, please let me know.

As you can see, Jewish, Acadian, and Native people are 100% endogamous, but many more Jewish people than Native people have tested, so you CAN’T judge endogamy by the total number of matches alone.

In fact, in order:

  • Fully Jewish testers have about 4-5 times as many matches as the Acadian and Non-endogamous testers
  • Acadian and Non-endogamous testers have about 5-6 times as many matches as the Native American testers
  • Fully Jewish people have about 30 times more matches than the Native American testers

If a person’s endogamy with a particular population is only on their maternal or paternal side, they won’t have a significant number of people related to both sides, meaning few people will fall into the “Both” bucket. People that will always be found in the ”Both” bucket are full siblings and their descendants, along with descendants of the tester, assuming their match is linked to their profiles in the tester’s tree.

In the case of our Jewish testers, you can easily see that the “Both” bucket is very high. The Acadians are also higher than one would reasonably expect without endogamy. A non-endogamous person might have a few matches on both sides, assuming the parents are not related to each other.

A high number of “Both” matches is a very good indicator of endogamy within the same population on both parents’ sides.

The percentage of people who are assigned to the “Both” bucket is between 11% and 14% in the endogamous groups, and less than 1% in the non-endogamous group, so statistically not relevant.

As demonstrated by the Native people compared to the Jewish testers, the total number of matches can be deceiving.

However, being related to both parents, as indicated by the “Both” bucket, unless you have pedigree collapse, is a good indicator of endogamy.

Of course, if you don’t know who your relatives are, you can’t link them in your tree, so this type of “hunt” won’t generally help people seeking their close family members.

However, you may notice that you’re matching people PLUS both of their parents. If that’s the case, start asking questions of those matches about their heritage.

A very high number of total matches, as compared to non-endogamous people, combined with some other hints might well point to Jewish heritage.

I included the % DNA Unassigned category because this category, when both parents are linked, is the percentage of matches by chance, meaning the match doesn’t match either of the tester’s parents. All of the people with people listed in “Both” categories have linked both of their parents, not just maternal and paternal relatives.

Matching Location at MyHeritage

MyHeritage provides a matching function by location. Please note that it’s the location of the tester, but that may still be quite useful.

The locations are shown in the most-matches to least-matches order. Clicking on the location shows the people who match you who are from that location. This would be the most useful in situations where recent immigration has occurred. In my case, my great-grandfather from the Netherlands arrived in the 1860s, and my German ancestors arrived in the 1850s. Neither of those groups are endogamous, though, unless it would be on a village level.

AutoClusters

Let’s shift to Genetic Affairs, a third-party tool available to everyone.

Using their AutoCluster function, Genetic Affairs clusters your matches together who match both each other and you.

This is an example of the first few clusters in my AutoCluster. You can see that I have several colored clusters of various sizes, but none are huge.

Compare that to the following endogamous cluster, sample courtesy of EJ Blom at Genetic Affairs.

If your AutoCluster at Genetic Affairs looks something like this, a huge orange blob in the upper left hand corner, you’re dealing with endogamy.

Please also note that the size of your cluster is also a function of both the number of testers and the match threshold you select. I always begin by using the defaults. I wrote about using Genetic Affairs, here.

If you tested at or transferred to MyHeritage, they too license AutoClusters, but have optimized the algorithm to tease out endogamous matches so that their Jewish customers, in particular, don’t wind up with a huge orange block of interrelated people.

You won’t see the “endogamy signature” huge cluster in the corner, so you’re less likely to be able to discern endogamy from a MyHeritage cluster alone.

The commonality between these Jewish clusters at MyHeritage is that they all tend to be rather uniform in size and small, with lots of grey connecting almost all the blocks.

Grey cells indicate people who match people in two colored groups. In other words, there is often no clear division in clusters between the mother’s side and the father’s side in Jewish clusters.

In non-endogamous situations, even if you can’t identify the parents, the clusters should still fall into two sides, meaning a group of clusters for each parent’s side that are not related to each other.

You can read more about Genetic Affairs clusters and their tools, here. DNAGedcom.com also provides a clustering tool.

Endogamous Relationships

Endogamous estimated relationships are sometimes high. Please note the word, “sometimes.”

Using the Shared cM Project tool relationship chart, here, at DNAPainter, people with heavy endogamy will discover that estimated relationships MAY be on the high side, or the relationships may, perhaps, be estimated too “close” in time. That’s especially true for more distant relationships, but surprisingly, it’s not always true. The randomness of inheritance still comes into play, and so do potential unknown relatives. Hence, the words “may” are bolded and underscored.

Unfortunately, it’s often stated as “conventional wisdom” that Jewish matches are “always” high, and first cousins appear as siblings. Let’s see what the actual data says.

At DNAPainter, you can either enter the amount of shared DNA (cM), or the percent of shared DNA, or just use the chart provided.

I’ve assembled a compilation of close relationships in kits that I have access to or from people who were generous enough to share their results for this article.

I’ve used Jewish results, which is a highly endogamous population, compared with non-endogamous testers.

The “Jewish Actual” column reports the total amount of shared DNA with that person. In other words, someone to their grandparent. The Average Range is the average plus the range from DNAPainter. The Percent Difference is the % difference between the actual number and the DNAPainter average.

You’ll see fully Jewish testers, at left, matching with their family members, and a Non-endogamous person, at right, matching with their same relative.

Relationship Jewish Actual Percent Difference than Average Average -Range Non-endogamous Actual Percent Difference than Average
Grandparent 2141 22 1754 (984-2482) 1742 <1 lower
Grandparent 1902 8.5 1754 (984-2482) 1973 12
Sibling 3039 16 2613 (1613-3488) 2515 3.5 lower
Sibling 2724 4 2613 (1613-3488) 2761 5.5
Half-Sibling 2184 24 1759 (1160-2436) 2127 21
Half-Sibling 2128 21 1759 (1160-2436) 2352 34
Aunt/Uncle 2066 18.5 1741 (1201-2282) 1849 6
Aunt/Uncle 2031 16.5 1741 (1201-2282) 2097 20
1C 1119 29 866 (396-1397) 959 11
1C 909 5 866 (396-1397) 789 9 lower
1C1R 514 19 433 (102-980) 467 8
1C1R 459 6 433 (102-980) 395 9 lower

These totals are from FamilyTreeDNA except one from GEDMatch (one Jewish Half-sibling).

Totals may vary by vendor, even when matching with the same person. 23andMe includes the X segments in the total cMs and also counts fully identical segments twice. MyHeritage imputation seems to err on the generous side.

However, in these dozen examples:

  • You can see that the Jewish actual amount of DNA shared is always more than the average in the estimate.
  • The red means the overage is more than 100 cM larger.
  • The percentage difference is probably more meaningful because 100 cM is a smaller percentage of a 1754 grandparent connection than compared to a 433 cM 1C1R.

However, you can’t tell anything about endogamy by just looking at any one sample, because:

  • Some of the Non-Endogamous matches are high too. That’s just the way of random inheritance.
  • All of the actual Jewish match numbers are within the published ranges, but on the high side.

Furthermore, it can get more complex.

Half Endogamous

I requested assistance from Jewish genealogy researchers, and a lovely lady, Sharon, reached out, compiled her segment information, and shared it with me, granting permission to share with you. A HUGE thank you to Sharon!

Sharon is half-Jewish via one parent, and her half-sibling is fully Jewish. Their half-sibling match to each other at Ancestry is 1756 cM with a longest segment of 164 cM.

How does Jewish matching vary if you’re half-Jewish versus fully Jewish? Let’s look at 21 people who match both Sharon and her fully Jewish half-sibling.

Sharon shared the differences in 21 known Jewish matches with her and her half-sibling. I’ve added the Relationship Estimate Range from DNAPainter and colorized the highest of the two matches in yellow. Bolding in the total cM column shows a value above the average range for that relationship.

Total Matching cMs is on the left, with Longest Segment on the right.

While this is clearly not a scientific study, it is a representative sample.

The fully Jewish sibling carries more Jewish DNA, which is available for other Jewish matches to match as a function of endogamy (identical by chance/population), so I would have expected the fully Jewish sibling to match most if not all Jewish testers at a higher level than the half-Jewish sibling.

However, that’s not universally what we see.

The fully Jewish sibling is not always the sibling with the highest number of matches to the other Jewish testers, although the half-Jewish tester has the larger “Longest Segment” more often than not.

Approximately two-thirds of the time (13/21), the fully Jewish person does have a higher total matching cM, but about one-third of the time (8/21), the half-Jewish sibling has a higher matching cM.

About one-fourth of the time (5/21), the fully Jewish sibling has the longest matching segment, and about two-thirds of the time (13/21), the half-Jewish sibling does. In three cases, or about 14% of the time, the longest segment is equal which may indicate that it’s the same segment.

Because of endogamy, Jewish matches are more likely to have:

  • Larger than average total cM for the specific relationship
  • More and smaller matching segments

However, as we have seen, neither of those are definitive, nor always true. Jewish matches and relationships are not always overestimated.

Ancestry and Timber

Please note that Ancestry downweights some matches by removing some segments using their Timber algorithm. Based on my matches and other accounts that I manage, Ancestry does not downweight in the 2-3rd cousin category, which is 90 cM and above, but they do begin downweighting in the 3-4th cousin category, below 90 cM, where my “Extended Family” category begins.

If you’ve tested at Ancestry, you can check for yourself.

By clicking on the amount of DNA you share with your match on your match list at Ancestry, shown above, you will be taken to another page where you will be able to view the unweighted shared DNA with that match, meaning the amount of DNA shared before the downweighting and removal of some segments, shown below.

Given the downweighting, and the information in the spreadsheet provided by Sharon, it doesn’t appear that any of those matches would have been in a category to be downweighted.

Therefore, for these and other close matches, Timber wouldn’t be a factor, but would potentially be in more distant matches.

Endogamous Segments

Endogamous matches tend to have smaller and more segments. Small amounts of matching DNA tend to skew the total DNA cM upwards.

How and why does this happen?

Ancestral DNA from further back in time tends to be broken into smaller segments.

Sometimes, especially in endogamous situations, two smaller segments, at one time separated from each other, manage to join back together again and form a match, but the match is only due to ancestral segments – not because of a recent ancestor.

Please note that different vendors have different minimum matching cM thresholds, so smaller matches may not be available at all vendors. Remember that factors like Timber and imputation can affect matching as well.

Let’s take a look at an example. I’ve created a chart where two ancestors have their blue and pink DNA broken into 4 cM segments.

They have children, a blue child and a pink child, and the two children, shown above, each inherited the same blue 4 cM segment and the same pink 4 cM segment from their respective parents. The other unlabeled pink and blue segments are not inherited by these two children, so those unlabeled segments are irrelevant in this example.

The parents may have had other children who inherited those same 4 cM labeled pink and blue segments as well, and if not, the parents’ siblings were probably passing at least some of the same DNA down to their descendants too.

The blue and pink children had children, and their children had children – for several generations.

Time passed, and their descendants became an endogamous community. Those pink and blue 4 cM segments may at some time be lost during recombination in the descendants of each of their children, shown by “Lost pink” and “Lost blue.”

However, because there is only a very limited amount of DNA within the endogamous community, their descendants may regain those same segments again from their “other parent” during recombination, downstream.

In each generation, the DNA of the descendant carrying the original blue or pink DNA segment is recombined with their partner. Given that the partners are both members of the same endogamous community, the two people may have the same pink and/or blue DNA segments. If one parent doesn’t carry the pink 4 cM segment, for example, their offspring may receive that ancestral pink segment from the other parent.

They could potentially, and sometimes do, receive that ancestral segment from both parents.

In our example, the descendants of the blue child, at left, lost the pink 4 cM segment in generation 3, but a few generations later, in generation 11, that descendant child inherited that same pink 4 cM segment from their other parent. Therefore, both the 4 cM blue and 4 cM pink segments are now available to be inherited by the descendants in that line. I’ve shown the opposite scenario in the generational inheritance at right where the blue segment is lost and regained.

Once rejoined, that pink and blue segment can be passed along together for generations.

The important part, though, is that once those two segments butt up against each other again during recombination, they aren’t just two separate 4 cM segments, but one segment that is 8 cM long – that is now equal to or above the vendors’ matching threshold.

This is why people descended from endogamous populations often have the following matching characteristics:

  • More matches
  • Many smaller segment matches
  • Their total cM is often broken into more, smaller segments

What does more, smaller segments, look like, exactly?

More, Smaller Segments

All of our vendors except Ancestry have a chromosome browser for their customers to compare their DNA to that of their matches visually.

Let’s take a look at some examples of what endogamous and non-endogamous matches look like.

For example, here’s a screen shot of a random Jewish second cousin match – 298 cM total, divided into 12 segments, with a longest segment of 58 cM,

A second Jewish 2C with 323 cM total, across 19 segments, with a 69 cM longest block.

A fully Acadian 2C match with 600 cM total, across 27 segments, with a longest segment of 69 cM.

A second Acadian 2C with 332 cM total, across 20 segments, with a longest segment of 42 cM.

Next, a non-endogamous 2C match with 217 cM, across 7 segments, with a longest segment of 72 cM.

Here’s another non-endogamous 2C example, with 169 shared cM, across 6 segments, with a longest segment of 70 cM.

Here’s the second cousin data in a summary table. The take-away from this is the proportion of total segments

Tester Population Total cM Longest Block Total Segments
Jewish 2C 298 58 12
Jewish 2C 323 69 19
Acadian 2C 600 69 27
Acadian 2C 332 42 20
Non-endogamous 2C 217 72 7
Non-endogamous 2C 169 70 6

You can see more examples and comparisons between Native American, Jewish and non-endogamous DNA individuals in the article, Concepts – Endogamy and DNA Segments.

I suspect that a savvy mathematician could predict endogamy based on longest block and total segment information.

Lara Diamond, a mathematician, who writes at Lara’s Jewnealogy might be up for this challenge. She just published compiled matching and segment information in her Ashkenazic Shared DNA Survey Results for those who are interested. You can also contribute to Laura’s data, here.

Endogamy, Segments, and Distant Relationships

While not relevant to searching for close relatives, heavily endogamous matches 3C and more distant, to quote one of my Jewish friends, “dissolve into a quagmire of endogamy and are exceedingly difficult to unravel.”

In my own Acadian endogamous line, I often simply have to label them “Acadian” because the DNA tracks back to so many ancestors in different lines. In other words, I can’t tell which ancestor the match is actually pointing to because the same DNA segments or segments is/are carried by several ancestors and their descendants due to founder effect.

The difference with the Acadians is that we can actually identify many or most of them, at least at some point in time. As my cousin, Paul LeBlanc, once said, if you’re related to one Acadian, you’re related to all Acadians. Then he proceeded to tell me that he and I are related 137 different ways. My head hurts!

It’s no wonder that endogamy is incredibly difficult beyond the first few generations when it turns into something like multi-colored jello soup.

“Are Your Parents Related?” Tool

There’s another tool that you can utilize to determine if your parents are related to each other.

To determine if your parents are related to each other, you need to know about ROH, or Runs of Homozygosity (ROH).

ROH means that the DNA on both strands or copies of the same chromosome is identical.

For a few locations in a row, ROH can easily happen just by chance, but the longer the segment, the less likely that commonality occurs simply by chance.

The good news is that you don’t need to know the identity of either of your parents. You don’t need either of your parent’s DNA tests – just your own. You’ll need to upload your DNA file to GEDmatch, which is free.

Click on “Are your parents related?”

GEDMatch analyzes your DNA to see if any of your DNA, above a reasonable matching threshold, is identical on both strands, indicating that you inherited the exact same DNA from both of your parents.

A legitimate match, meaning one that’s not by chance, will include many contiguous matching locations, generally a minimum of 500 SNPs or locations in a row. GEDmatch’s minimum threshold for identifying identical ancestral DNA (ROH) is 200 cM.

Here’s my result, including the graphic for the first two chromosomes. Notice the tiny green bars that show identical by chance tiny sliver segments.

I have no significant identical DNA, meaning my parents are not related to each other.

Next, let’s look at an endogamous example where there are small, completely identical segments across a person’s chromosome

This person’s Acadian parents are related to each other, but distantly.

Next, let’s look at a Jewish person’s results.

You’ll notice larger green matching ROH, but not over 200 contiguous SNPs and 7 cM.

GEDMatch reports that this Jewish person’s parents are probably not related within recent generations, but it’s clear that they do share DNA in common.

People whose parents are distantly related have relatively small, scattered matching segments. However, if you’re seeing larger ROH segments that would be large enough to match in a genealogical setting, meaning multiple greater than 7 cM and 500 SNPs,, you may be dealing with a different type of situation where cousins have married in recent generations. The larger the matching segments, generally, the closer in time.

Blogger Kitty Cooper wrote an article, here, about discovering that your parents are related at the first cousin level, and what their GEDMatch “Are Your Parents Related” results look like.

Let’s look for more clues.

Surnames

There MAY be an endogamy clue in the surnames of the people you match.

Viewing surnames is easier if you download your match list, which you can do at every vendor except Ancestry. I’m not referring to the segment data, but the information about your matches themselves.

I provided instructions in the recent article, How to Download Your DNA Match Lists and Segment Files, here.

If you suspect endogamy for any reason, look at your closest matches and see if there is a discernable trend in the surnames, or locations, or any commonality between your matches to each other.

For example, Jewish, Acadian, and Native surnames may be recognizable, as may locations.

You can evaluate in either or both of two ways:

  • The surnames of your closest matches. Closest matches listed first will be your default match order.
  • Your most frequently occurring surnames, minus extremely common names like Smith, Jones, etc., unless they are also in your closest matches. To utilize this type of matching, sort the spreadsheet in surname order and then scan or count the number of people with each surname.

Here are some examples from our testers.

Jewish – Closest surname matches.

  • Roth
  • Weiss
  • Goldman
  • Schonwald
  • Levi
  • Cohen
  • Slavin
  • Goodman
  • Sender
  • Trebatch

Acadian – Closest surname matches.

  • Bergeron
  • Hebert
  • Bergeron
  • Marcum
  • Muise
  • Legere
  • Gaudet
  • Perry
  • Verlander
  • Trombley

Native American – Closest surname matches.

  • Ortega
  • Begay
  • Valentine
  • Hayes
  • Montoya
  • Sun Bear
  • Martin
  • Tsosie
  • Chiquito
  • Yazzie

You may recognize these categories of surnames immediately.

If not, Google is your friend. Eliminate common surnames, then Google for a few together at a time and see what emerges.

The most unusual surnames are likely your best bets.

Projects

Another way to get some idea of what groups people with these surnames might belong to is to enter the surname in the FamilyTreeDNA surname search.

Go to the main FamilyTreeDNA page, but DO NOT sign on.

Scroll down until you see this image.

Type the surname into the search box. You’ll see how many people have tested with that surname, along with projects where project administrators have included that surname indicating that the project may be of interest to at least some people with that surname.

Here’s a portion of the project list for Cohen, a traditional Jewish surname.

These results are for Muise, an Acadian surname.

Clicking through to relevant surname projects, and potentially contacting the volunteer project administrator can go a very long way in helping you gather and sift information. Clearly, they have an interest in this topic.

For example, here’s the Muise surname in the Acadian AmerIndian project. Two great hints here – Acadian heritage and Halifax, Nova Scotia.

Repeat for the balance of surnames on your list to look for commonalities, including locations on the public project pages.

Locations

Some of the vendor match files include location information. Each person on your match list will have the opportunity at the vendor where they tested to include location information in a variety of ways, either for their ancestors or themselves.

Where possible, it’s easiest to sort or scan the download file for this type of information.

Ancestry does not provide or facilitate a match list, but you can still create your own for your closest 20 or 30 matches in a spreadsheet.

MyHeritage provides common surname and ancestral location information for every match. How cool is that!

Y DNA, Mitochondrial DNA, and Endogamy

Haplogroups for both Y and mitochondrial DNA can indicate and sometimes confirm endogamy. In other cases, the haplogroup won’t help, but the matches and their location information just might.

FamilyTreeDNA is the only vendor that provides Y DNA and mitochondrial DNA tests that include highly granular haplogroups along with matches and additional tools.

23andMe provides high-level haplogroups which may or may not be adequate to pinpoint a haplogroup that indicates endogamy.

Of course, only males carry Y DNA that tracks to the direct paternal (surname) line, but everyone carries their mother’s mitochondrial DNA that represents their mother’s mother’s mother’s, or direct matrilineal line.

Some haplogroups are known to be closely associated with particular ethnicities or populations, like Native Americans, Pacific Islanders, and some Jewish people.

Haplogroups reach back in time before genealogy and can give us a sense of community that’s not available by either looking in the mirror or through traditional records.

This Native American man is a member of high-level haplogroup Q-M242. However, some men who carry this haplogroup are not Native, but are of European or Middle Eastern origin.

I entered the haplogroup in the FamilyTreeDNA Discover tool, which I wrote about, here.

Checking the information about this haplogroup reveals that their common ancestor descended from an Asian man about 30,000 years ago.

The migration path in the Americans explains why this person would have an endogamous heritage.

Our tester would receive a much more refined haplogroup if he upgraded to the Big Y test at FamilyTreeDNA, which would remove all doubt.

However, even without additional testing, information about his matches at FamilyTreeDNA may be very illuminating.

The Q-M242 Native man’s Y DNA matches men with more granular haplogroups, shown above, at left. On the Haplogroup Origins report, you can see that these people have all selected the “US (Native American)” country option.

Another useful tool would be to check the public Y haplotree, here, and the public mitochondrial tree here, for self-reported ancestor location information for a specific haplogroup.

Here’s an example of mitochondrial haplogroup A2 and a few subclades on the public mitochondrial tree. You can see that the haplogroup is found in Mexico, the US (Native,) Canada, and many additional Caribbean, South, and Central American countries.

Of course, Y DNA and mitochondrial DNA (mtDNA) tell a laser-focused story of one specific line, each. The great news, if you’re seeking information about your mother or father, the Y is your father’s direct paternal (surname) line, and mitochondrial is your mother’s direct matrilineal line.

Y and mitochondrial DNA results combined with ethnicity, autosomal matching, and the wide range of other tools that open doors, you will be able to reveal a great deal of information about whether you have endogamous heritage or not – and if so, from where.

I’ve provided a resource for stepping through and interpreting your Y DNA results, here, and mitochondrial DNA, here.

If you’re a female, you may feel left out of Y DNA testing and what it can tell you about your heritage. However, there’s a back door.

You can utilize the Y DNA haplogroups of your closest autosomal matches at both FamilyTreeDNA and 23andMe to reveal information

Haplogroup information is available in the download files for both vendors, in addition to the Family Finder table view, below, at FamilyTreeDNA, or on your individual matches profile cards at both 23andMe and FamilyTreeDNA.

You can enter any Y DNA haplogroup in the FamilyTreeDNA Discover tool, here.

You’ll be treated to:

  • Your Haplogroup Story – how many testers have this haplogroup (so far), where the haplogroup is from, and the haplogroup’s age. In this case, the haplogroup was born in the Netherlands about 250 years ago, give or take 200 years. I know that it was 1806 or earlier based on the common ancestor of the men who tested.
  • Country Frequency – heat map of where the haplogroup is found in the world.
  • Notable Connections – famous and infamous (this haplogroup’s closest notable person is Leo Tolstoy).
  • Migration Map – migration path out of Africa and through the rest of the world.
  • Ancient Connections – ancient burials. His closest ancient match is from about 1000 years ago in Ukraine. Their shared ancestor lived about 2000 years ago.
  • Suggested Projects – based on the surname, projects that other matches have joined, and haplogroups.
  • Scientific Details – age estimates, confidence intervals, graphs, and the mutations that define this haplogroup.

I wrote about the Discover tool in the article, FamilyTreeDNA DISCOVER Launches – Including Y DNA Haplogroup Ages.

Endogamy Tools Summary Tables

Endogamy is a tough nut sometimes, especially if you’re starting from scratch. In order to make this topic a bit easier and to create a reference tool for you, I’ve created three summary tables.

  • Various endogamy-related tools available at each vendor which will or may assist with evaluating endogamy
  • Tools and their ability to detect endogamy in different groups
  • Tools best suited to assist people seeking information about unknown parents or grandparents

Summary of Endogamy Tools by Vendor

Please note that GEDMatch is not a DNA testing vendor, but they accept uploads and do have some tools that the testing vendors do not.

 Tool 23andMe Ancestry FamilyTreeDNA MyHeritage GEDMatch
Ethnicity Yes Yes Yes Yes Use the vendors
Ethnicity Painting Yes + segments Yes, limited Yes + segments Yes

Summary of Endogamous Populations Identified by Each Tool

The following chart provides a guideline for which tools are useful for the following types of endogamous groups. Bolded tools require that both parents be descended from the same endogamous group, but several other tools give more definitive results with higher amounts of endogamy.

Y and mitochondrial DNA testing are not affected by admixture, autosomal DNA or anything from the “other” parent.

Ethnicity Painting Yes No No Yes Pacific Islander
Ethnicity Phasing Yes, if different No No Yes, if different Pacific Islander, if different

Summary of Endogamy Tools to Assist People Seeking Unknown Parents and Grandparents

This table provides a summary of when each of the various tools can be useful to:

  • People seeking unknown close relatives
  • People who already know who their close relatives are, but are seeking additional information or clues about their genealogy

I considered rating these on a 1 to 10 scale, but the relative usefulness of these tools is dependent on many factors, so different tools will be more or less useful to different people.

For example, ethnicity is very useful if someone is admixed from different populations, or even 100% of a specific endogamous population. It’s less useful if the tester is 100% European, regardless of whether they are seeking close relatives or not. Conversely, even “vanilla” ethnicity can be used to rule out majority or recent admixture with many populations.

Tools Unknown Close Relative Seekers Known Close Relatives – Enhance Genealogy
Ethnicity Yes, to identify or rule out populations Yes
Ethnicity Painting Yes, possibly, depending on population Yes, possibly, depending on population
Ethnicity Phasing Yes, possibly, depending on population Yes, possibly, depending on population
DNA Communities Yes, possibly, depending on population Yes, possibly, depending on population
Genetic Groups Possibly, depending on population Possibly, depending on population
Family Matching aka Bucketing Not if parents are entirely unknown, but yes if one parent is known Yes
Chromosome Browser Unlikely Yes
AutoClusters Yes Yes, especially at MyHeritage if Jewish
Estimated Relationships High Not No
Relationship Range High Not reliably No
More, Smaller Segments Unlikely Unlikely other than confirmation

In Search of…Vendor Features, Strengths, and Testing Strategies

This is the third in our series of articles about searching for unknown close family members, specifically; parents, grandparents, or siblings. However, these same techniques can be applied to ancestors further back in time too.

In this article, we are going to discuss your goals and why testing or uploading to multiple vendors is advantageous – even if you could potentially solve the initial mystery at one vendor. Of course, the vendor you test with first might not be the vendor where the mystery will be solved, and data from multiple vendors might just be the combination you need.

Testing Strategy – You Might Get Lucky

I recommended in the first article that you go ahead and test at the different vendors.

Some people asked why, and specifically, why you wouldn’t just test at one vendor with the largest database first, then proceed to the others if you needed to.

That’s a great question, and I want to discuss the pros and cons in this article more specifically.

Clearly, that is one strategy, but the approach you select might differ based on a variety of considerations:

  • You may only be interested in obtaining the name of the person you are seeking – or – you may be interested in finding out as much as possible.
  • You may find that your best match at one company is decidedly unhelpful, and may even block you or your efforts, while someone elsewhere may be exactly the opposite.
  • Solving your mystery may be difficult and painful at one vendor, but the answer may be infinitely easier at a different vendor where the answer may literally be waiting.
  • There may not be enough, or the right information, or matches, at any one vendor, but the puzzle may be solvable by combining information from multiple vendors and tests. Every little bit helps.
  • You may have a sense of urgency, especially if you hope to meet the person and you’re searching for parents, siblings or grandparents who may be aging.
  • You may be cost-sensitive and cannot afford more than one test at a time. Fortunately, our upload strategy helps with that too. Also, watch for vendor sales or bundles.

From the time you order your DNA test, it will be about 6-8 weeks, give or take a week or two in either direction, before you receive results.

When those results arrive, you might get lucky, and the answer you seek is immediately evident with no additional work and just waiting for you at the first testing company.

If that’s the case, you got lucky and hit the jackpot. If you’re searching for both parents, that means you still have one parent to go.

Unidentified grandparents can be a little more difficult, because there are four of them to sort between.

If you discover a sibling or half-sibling, you still need to figure out who your common parent is. Sometimes X, Y, and mitochondrial DNA provides an immediate answer and is invaluable in these situations.

It’s more likely that you’ll find a group of somewhat more distant relatives. You may be able to figure out who your common grandparents or great-grandparents are, but not your parent(s) initially. Often, the closer generation or two is actually the most difficult because you’re dealing with contemporary records which are not publicly available, fewer descendants, and the topic may be very uncomfortable for some people. It’s also complicated because you’re often not dealing with “full” relationships, but “half,” as in half-sibling, half-niece, half-1C, etc.

You may spend a substantial amount of time trying to solve this puzzle at the first vendor before ordering your next test.

That second test will also take about 6-8 weeks, give or take. I recommend that you order the first two autosomal tests, now.

Order Your First Two Autosomal Tests

The two testing companies with the largest autosomal databases for comparison, Ancestry, and 23andMe, DO NOT accept DNA file uploads from other companies, so you’ll need to test with each individually.

Fortunately, you CAN transfer your autosomal DNA tests to both MyHeritage and FamilyTreeDNA, for free.

You will have different matches at each company. Some people will be far more responsive and helpful than others.

I recommend that you go ahead and order both the Ancestry and 23andMe tests initially, then upload the first one that comes back with results to both FamilyTreeDNA and MyHeritage. Complete, step-by-step download/upload instructions can be found here.

You can also upload your DNA file to a fifth company, Living DNA, but they are significantly smaller and heavily focused on England and Great Britain. However, if that’s where you’re searching, this might be where you find important matches.

You can also upload to GEDMatch, a popular third-party database, but since you’re going to be in the databases of the four major testing companies, there is little to be gained at GEDMatch in terms of people who have not tested at one of the major companies. Do NOT upload to GEDMatch INSTEAD of testing or uploading to the four major sites, as GEDMatch only has a small fraction of the testers in each of the vendor databases.

What GEDMatch does offer is a chromosome browser – something that Ancestry does NOT offer, along with other clustering tools which you may find useful. I recommend GEDMatch in addition to the others, if needed or desired.

Ordering Y and Mitochondrial DNA Tests

We reviewed the basics of the different kinds of DNA, here.

Some people have asked why, if autosomal DNA shows relatives on all of your lines, would one would want to order specific tests that focus on just one line?

It just so happens that the two lines that Y and mitochondrial DNA test ARE the two lines you’re seeking – direct maternal – your mother (and her mother), and direct paternal, your father (and his father.)

These two tests are different kinds of DNA tests, testing a different type of DNA, and provide very focused information, and matches, not available from autosomal DNA tests.

For men, Y DNA can reveal your father’s surname, which can be an invaluable clue in narrowing paternal candidates. Knowing that my brother’s Y DNA matched several men with the surname of Priest made me jump for joy when he matched a woman of that same last name at another vendor.

Here’s a quote from one of the members of a Y DNA project where I’m the volunteer administrator:

“Thank you for your help understanding and using all 4 kinds of my DNA results. By piecing the parts together, I identified my father. Specifically, without Y DNA testing, and the Big Y test, I would not have figured out my parental connection, and then that my paternal line had been assigned to the wrong family. STR testing gave me the correct surname, but the Big Y test showed me exactly where I fit, and disproved that other line. I’m now in touch with my father, and we both know who our relatives are – two things that would have never happened otherwise.”

If you fall into the category of, “I want to know everything I can now,” then order both Y and mitochondrial DNA tests initially, along with those two autosomal tests.

You will need to order Y (males only) and mitochondrial DNA tests separately from the autosomal Family Finder test, although you should order on the same account as your Family Finder test at FamilyTreeDNA.

If you take the Family Finder autosomal test at FamilyTreeDNA or upload your autosomal results from another vendor, you can simply select to add the Y and mitochondrial DNA tests to your account, and they will send you a swab kit.

Conversely, you can order either a Y or mitochondrial DNA test, and then add a Family Finder or upload a DNA file if you’ve already taken an autosomal DNA test to that account too. Note – these might not be current prices – check here for sales.

You will want all 3 of your tests on the same account so that you can use the Advanced Matches feature.

Using Advanced Matches, you’ll be able to view people who match you on combinations of multiple kinds of tests.

For example, if you’re a male, you can see if your Y DNA matches also match you on the Family Finder autosomal test, and if so, how closely?

Here’s an example.

In this case, I requested matches to men with 111 markers who also match the tester on the Family Finder test. I discovered both a father and a full sibling, plus a few more distant matches. There were ten total combined matches to work with, but I’ve only shown five for illustration purposes.

This information is worth its weight in gold.

Is the Big Y Test Worth It?

People ask if the Big Y test is really worth the extra money.

The answer is, “it depends.”

If all you’re looking for are matching surnames, then the answer is probably no. A 37 or 111 marker test will probably suffice. Eventually, you’ll probably want to do the Big Y, though.

If you’re looking for exact placement on the tree, with an estimated distance to other men who have taken that test, then the answer is, “absolutely.” I wish the Big Y test had been available back when I was hunting for my brother’s biological family.

The Big Y test provides a VERY specific haplogroup and places you very accurately in your location on the Y DNA tree, along with other men of your line, assuming they have tested. You may find the surname, as well as being placed within a generation or a few of current in that family line.

Additionally, the Discover page provides estimates of how far in the past you share a common ancestor with other people that share the same haplogroup. This can be a HUGE boon to a male trying to figure out his surname line and how closely in time he’s related to his matches.

Big Y NPE Examples

Y DNA SNP mutations tested with the Big Y test accrue a mutation about every generation, or so. Sometimes we see mutations in every generation.

Here’s an example from my Campbell line. Haplogroups are listed in the top three rows.

I created this spreadsheet, but FamilyTreeDNA provides a block tree for Big Y testers. I’ve added the genealogy of the testers, with the various Big Y testers at the bottom and common ancestors above, in bold.

We have two red NPE lines showing. The MacFarlane tester matches M. Campbell VERY closely, and two Clark males match W. Campbell and other Campbells quite closely. We utilized autosomal plus the Y results to determine where the unknown parentage events occurred. Today, if you’re a Clark or MacFarlane male, or a male by any other surname who was fathered by a Y chromosome Campbell male (by any surname), you’ll know exactly where you fit in this group of testers on your direct paternal line.

Y DNA is important because men often match other men with the same surname, which is a HUGE clue, especially in combination with autosomal DNA results. I say “often,” because it’s possible that no one in your line has tested, or that your father’s surname is not his biological surname either.

Y and mitochondrial DNA matches can be HUGELY beneficial pieces of information either by confirming a close autosomal relationship on that line, or eliminating the possibility.

Lineage-Specific Population Information

In addition to matching other people, both Y and mitochondrial DNA tests provide you with lineage-specific population or “ethnicity” information for this specific line which helps you focus your research.

For example, if you view the Y DNA Haplogroup Origins shown for this tester, you’ll discover that these matches are Jewish.

The tester might not be Jewish on any other genealogical line, but they definitely have Jewish ancestry on their Y DNA, paternal, line.

The same holds true for mitochondrial DNA as well. The main difference with mitochondrial DNA is that the surname changes with each generation, haplogroups today (pre-Million Mito) are less specific, and fewer people have been tested.

Y and Mitochondrial DNA Benefits

Knowing your Y and mitochondrial DNA haplogroups not only arm you with information about yourself, they provide you with matching tools and an avenue to include or exclude people as your direct line paternal or maternal ancestors.

Your Y and mitochondrial DNA can also provide CRITICALLY IMPORTANT information about whether that direct line ancestor belonged to an endogamous population, and where they came from.

For example, both Jewish and Native populations are endogamous populations, meaning highly intermarried for many generations into the past.

Knowing that helps you adjust your autosomal relationship analysis.

Why Order Multiple Tests Initially Instead of Waiting?

If you’ve been adding elapsed time, two autosomal tests (Ancestry and 23andMe), two uploads (to FamilyTreeDNA and MyHeritage,) a Y DNA test, and a mitochondrial DNA test, if all purchased serially, one following the other, means you’ll be waiting approximately 6-8 months.

Do you want to wait 6-8 months for all of your results? Can you afford to?

Part of this answer has to do with what, exactly, you’re seeking, and how patient you are.

Only you can answer that question.

A Name or Information?

Are you seeking the name or identity of a person, or are you seeking information about that person?

Most people don’t just want to put a name to the person they are seeking – they want to learn about them and the rest of the family that door opens.

You will have different matches at each company. Even after you identify the person you seek, the people you match may have trees you can view, with family photos and other important information. (Remember, you can’t see living people in trees.) Your matches may have first-person information about your relative and may know them if they are living, or have known them.

Furthermore, you may have the opportunity to meet that person. Time delayed may not be able to be recovered or regained.

One cousin that I assisted discovered that his father had died just six weeks before he broke through that wall and made the connection.

Working with data from all vendors simultaneously will allow you to combine that data and utilize it together. Using your “best” matches at each company, augmented by X, Y, and/or mitochondrial DNA, can make MUCH shorter work of this search.

Your closest autosomal matches are the most important and insightful. In this series, I will be working with the top 15 autosomal results at each vendor, at least initially. This approach provides me with the best chance of meaningful close relationship discoveries.

Data and Vendor Results Integration

Here’s a table of my two closest maternal and paternal matches at the four major vendors. I can assign these to maternal or paternal sides, because I know the identity of my parents, and I know some of these people. If an adoptee was doing this, the top 4 could all be from one parent, which is why we work with the top 15 or so matches.

Vendor Closest Maternal Closest Paternal Comments
Ancestry 1C, 1C1R Half-1C, 2C I recognized both of the maternal and neither of the paternal.
23andMe 2C, 2C 1C1R, half-gr-niece Recognized both maternal, one paternal
MyHeritage Mother uploaded, 1C Half-niece, half-1C Recognized both maternal, one paternal
FamilyTreeDNA Mother tested, 1C1R Parent/child, half-gr-niece uploaded Recognized all 4

To be clear, I tested my mother’s mitochondrial DNA before she passed away, but because FamilyTreeDNA archives DNA samples for 25 years, as the owner/manager of her DNA kit, I was able to order the Family Finder test after she had passed away. Her tests are invaluable today.

Then, years later, I uploaded her results to MyHeritage.

If I was an adopted child searching for my mother, I would find her results in both databases today. She’ll never be at either 23andMe or Ancestry because she passed away before she could test there and they don’t accept uploads.

Looking at the other vendors, my half-niece at MyHeritage is my paternal half-sibling’s daughter. My half-sibling is deceased, so this is as close as I’ll ever get to matching her.

At 23andMe, the half-great-niece is my half-siblings grandchild.

It’s interesting that I have no matches to descendants of my other half-sibling, who is also deceased. Maybe I should ask if any of his children or grandchildren have tested. Hmmmm…..

You can see that I stand a MUCH BETTER chance of figuring out close relatives using the combined closest matches of all four databases instead of the top matches from just one database. It doesn’t matter if the database is large if the right person or people didn’t test there.

Combine Resources

I’ll be providing analysis methodologies for working with results from all of the vendors together, just in case your answer is not immediately obvious. Taking multiple DNA tests facilitates using all of these tools immediately, not months later. Solving the puzzle sooner means you may not miss valuable opportunities.

You may also discover that the door slams shut with some people, or they may not respond to your queries, but another match may be unbelievably helpful. Don’t limit your possibilities.

Let’s take a look at the strengths of each vendor.

Vendor Strengths and Things to Know

Every vendor has product strengths and idiosyncracies that the others do not. All vendors provide matches and shared matches. Each vendor provides ethnicity tools which certainly can be useful, but the features differ and will be covered elsewhere.

  • AncestryAncestry has the largest autosomal database and includes ThruLines, but no Y or mitochondrial DNA testing, no clusters, no chromosome browser, no triangulation, and no X chromosome matching or reporting. Ancestry provides genealogical records, advanced tools, and full tree access to your matches’ trees with an Ancestry subscription. Ancestry does not allow downloading your match list or segment match information, but the other vendors do.
  • 23andMe 23andMe has the second largest database. They provide triangulation and genetic trees that include your closest matches. Many people test at 23andMe for health and wellness information, so 23andMe has people in their database who are not specifically interested in genealogy and probably won’t have tested elsewhere, but may be invaluable to your search. 23andMe provides Y and mtDNA high-level haplogroups only, but no matching or other haplogroup information. If you purchase a new test or have a V5 ancestry+health current test, you can expand your matches from a limit of 1500 to about 5000 with an annual membership. For seeking close relatives, you don’t need those features, but you may want them for genealogy. 23andMe is the only vendor that limits their customers’ matches.
  • MyHeritageMyHeritage has the third largest database that includes lots of European testers. MyHeritage provides triangulation, Theories of Family Relativity, and an integrated cluster tool* but does not report X matches and does not offer Y or mitochondrial DNA testing. MyHeritage accepts autosomal DNA file uploads from other testing companies for free and provides access to advanced DNA features for a one-time unlock fee. MyHeritage includes genealogical records and full feature access to advanced DNA tools with a Complete Subscription. (Free 15 days trial subscription, here.)
  • FamilyTreeDNA Family Finder (autosomal)FamilyTreeDNA is the oldest DNA testing company, meaning their database includes people who initially tested 20+ years ago and have since passed away. This, in essence, gets you one generation further back in time, with the possibility of stronger matches. Their Family Matching feature buckets and triangulates your matches, assigning them to your maternal or paternal sides if you link known matches to their proper place in your tree, even if your parents have not tested. FamilyTreeDNA accepts uploads from other testing companies for free and provides advanced DNA features for a one time unlock fee.
  • FamilyTreeDNAFamilyTreeDNA is the only company that offers both Y and mitochondrial DNA testing products that include matching, integration with autosomal test results, and other tools. These two tests are lineage-specific and don’t have to be sorted from your other ancestral lines.

I wrote about using Y DNA results, here.

I wrote about using mitochondrial DNA results, here.

*Third parties such as Genetic Affairs provide clustering tools for both 23andMe and FamilyTreeDNA. Clustering is integrated at MyHeritage. Ancestry does not provide a tool for nor allow third-party clustering. If the answer you seek isn’t immediately evident, Genetic Affairs clustering tools group people together who are related to each other, and you, and create both genetic and genealogical trees based on shared matches. You can read more about their tools, here.

Fish in all the Ponds and Use All the Bait Possible

Here’s the testing and upload strategy I recommend, based on the above discussion and considerations. The bottom line is this – if you want as much information as possible, as quickly as possible, order the four tests in red initially. Then transfer the first autosomal test results you receive to the two companies identified in blue. Optionally, GEDMatch may have tools you want to work with, but they aren’t a testing company.

What When Ancestry 23andMe MyHeritage FamilyTreeDNA
Order autosomal Initially X X    
Order Y 111 or Big-Y DNA test if male Initially       X
Order mitochondrial DNA test Initially if desired       X
Upload free autosomal When Ancestry or 23andMe results are available     X X
Unlock Advanced Tools When you upload     $29 $19
Optional GEDMatch free upload If desired, can subscribe for advanced tools

When you upload an autosomal DNA file to a vendor site, only upload one file per site, per tester. Otherwise, multiple tests simply glom up everyone’s match list with multiple matches to the same person.

Multiple vendor sites will hopefully provide multiple close matches, which increase your opportunity to discover INFORMATION about your family, not just the identity of the person you seek.

Or maybe you prefer to wait and order these DNA tests serially, waiting until one set of results is back and you’re finished working with them before ordering the next one. If so, that means you’re a MUCH more patient person than me. 😊

Our next article in this series will be about endogamy, how to know if it applies to you, and what that means to your search.

FamilyTreeDNA DISCOVER™ Launches – Including Y DNA Haplogroup Ages

FamilyTreeDNA just released an amazing new group of public Y DNA tools.

Yes, a group of tools – not just one.

The new Discover tools, which you can access here, aren’t just for people who have tested at FamilyTreeDNA . You don’t need an account and it’s free for everyone. All you need is a Y DNA haplogroup – from any source.

I’m going to introduce each tool briefly because you’re going to want to run right over and try Discover for yourself. In fact, you might follow along with this article.

Y DNA Haplogroup Aging

The new Discover page provides seven beta tools, including Y DNA haplogroup aging.

Haplogroup aging is THE single most requested feature – and it’s here!

Discover also scales for mobile devices.

Free Beta Tool

Beta means that FamilyTreeDNA is seeking your feedback to determine which of these tools will be incorporated into their regular product, so expect a survey.

If you’d like changes or something additional, please let FamilyTreeDNA know via the survey, their support line, email or Chat function.

OK, let’s get started!

Enter Your Haplogroup

Enter your Y DNA haplogroup, or the haplogroup you’re interested in viewing.

If you’re a male who has tested with FamilyTreeDNA , sign on to your home page and locate your haplogroup badge at the lower right corner.

If you’re a female, you may be able to test a male relative or find a haplogroup relevant to your genealogy by visiting your surname group project page to locate the haplogroup for your ancestor.

I’ll use one of my genealogy lines as an example.

In this case, several Y DNA testers appear under my ancestor, James Crumley, in the Crumley DNA project.

Within this group of testers, we have two different Big Y haplogroups, and several estimated haplogroups from testers who have not upgraded to the Big Y.

If you’re a male who has tested at either 23andMe or LivingDNA, you can enter your Y DNA haplogroup from that source as well. Those vendors provide high-level haplogroups.

The great thing about the new Discover tool is that no matter what haplogroup you enter, there’s something for you to enjoy.

I’m going to use haplogroup I-FT272214, the haplogroup of my ancestor, James Crumley, confirmed through multiple descendants. His son John’s descendants carry haplogroup I-BY165368 in addition to I-FT272214, which is why there are two detailed haplogroups displayed for this grouping within the Crumley haplogroup project, in addition to the less-refined I-M223.

Getting Started

When you click on Discover, you’ll be asked to register briefly, agree to terms, and provide your email address.

Click “View my report” and your haplogroup report will appear.

Y DNA Haplogroup Report

For any haplogroup you enter, you’ll receive a haplogroup report that includes 7 separate pages, shown by tabs at the top of your report.

Click any image to enlarge

The first page you’ll see is the Haplogroup Report.

On the first page, you’ll find Haplogroup aging. The TMRCA (time to most recent common ancestor) is provided, plus more!

The report says that haplogroup I-FT272214 was “born,” meaning the mutation that defines this haplogroup, occurred about 300 years ago, plus or minus 150 years.

James Crumley was born about 1710. We know his sons carry haplogroup I-FT272214, but we don’t know when that mutation occurred because we don’t have upstream testers. We don’t know who his parents were.

Three hundred years before the birth of our Crumley tester would be about 1670, so roughly James Crumley’s father’s generation, which makes sense.

James’ son John’s descendants have an additional mutation, so that makes sense too. SNP mutations are known to occur approximately every 80 years, on average. Of course, you know what average means…may not fit any specific situation exactly.

The next upstream haplogroup is I-BY100549 which occurred roughly 500 years ago, plus or minus 150 years. (Hint – if you want to view a haplogroup report for this upstream haplogroup, just click on the haplogroup name.)

There are 5 SNP confirmed descendants of haplogroup I-FT272214 claiming origins in England, all of whom are in the Crumley DNA project.

Haplogroup descendants mean this haplogroup and any other haplogroups formed on the tree beneath this haplogroup.

Share

If you scroll down a bit, you can see the share button on each page. If you think this is fun, you can share through a variety of social media resources, email, or copy the link.

Sharing is a good way to get family members and others interested in both genealogy and genetic genealogy. Light the spark!

I’m going to be sharing with collaborative family genealogy groups on Facebook and Twitter. I can also share with people who may not be genealogists, but who will think these findings are interesting.

If you keep scrolling under the share button or click on “Discover More” you can order Y DNA tests if you’re a biological male and haven’t already taken one. The more refined your haplogroup, the more relevant your information will be on the Discover page as well as on your personal page.

Scrolling even further down provides information about methods and sources.

Country Frequency

The next tab is Country Frequency showing the locations where testers with this haplogroup indicate that their earliest known ancestors are found.

The Crumley haplogroup has only 5 people, which is less than 1% of the people with ancestors from England.

However, taking a look at haplogroup R-M222 with many more testers, we see something a bit different.

Ireland is where R-M222 is found most frequently. 17% of the men who report their ancestors are from Ireland belong to haplogroup R-M222.

Note that this percentage also includes haplogroups downstream of haplogroup R-M222.

Mousing over any other location provides that same information for that area as well.

Seeing where the ancestors of your haplogroup matches are from can be extremely informative. The more refined your haplogroup, the more useful these tools will be for you. Big Y testers will benefit the most.

Notable Connections

On the next page, you’ll discover which notable people have haplogroups either close to you…or maybe quite distant.

Your first Notable Connection will be the one closest to your haplogroup that FamilyTreeDNA was able to identify in their database. In some cases, the individual has tested, but in many cases, descendants of a common ancestor tested.

In this case, Bill Gates is our closest notable person. Our common haplogroup, meaning the intersection of Bill Gates’s haplogroup and my Crumley cousin’s haplogroup is I-L1195. The SNP mutation that defines haplogroup I-L1145 occurred about 4600 years ago. Both my Crumley cousin and Bill Gates descend from that man.

If you’re curious and want to learn more about your common haplogroup, remember, you can enter that haplogroup into the Discover tool. Kind of like genetic time travel. But let’s finish this one first.

Remember that CE means current era, or the number of years since the year “zero,” which doesn’t technically exist but functions as the beginning of the current era. Bill Gates was born in 1955 CE

BCE means “before current era,” meaning the number of years before the year “zero.” So 2600 BCE is approximately 4600 years ago.

Click through each dot for a fun look at who you’re “related to” and how distantly.

This tool is just for fun and reinforces the fact that at some level, we’re all related to each other.

Maybe you’re aware of more notables that could be added to the Discover pages.

Migration Map

The next tab provides brand spanking new migration maps that show the exodus of the various haplogroups out of Africa, through the Middle East, and in this case, into Europe.

Additionally, the little shovel icons show the ancient DNA sites that date to the haplogroup age for the haplogroup shown on the map, or younger. In our case, that’s haplogroup I-M223 (red arrow) that was formed about 16,000 years ago in Europe, near the red circle, at left. These haplogroup ancient sites (shovels) would all date to 16,000 years ago or younger, meaning they lived between 16,000 years ago and now.

By clicking on a shovel icon, more information is provided. It’s very interesting that I-L1145, the common haplogroup with Bill Gates is found in ancient DNA in Cardiff, Wales.

This is getting VERY interesting. Let’s look at the rest of the Ancient Connections.

Ancient Connections

Our closest Ancient Connection in time is Gen Scot 24 (so name in an academic paper) who lived in the Western Isles of Scotland.

These ancient connections are more likely cousins than direct ancestors, but of course, we can’t say for sure. We do know that the first man to develop haplogroup I-L126, about 2500 years ago, is an ancestor to both Gen Scot 24 and our Crumley ancestor.

Gen Scot 24 has been dated to 1445-1268 BCE which is about 3400 years ago, which could actually be older than the haplogroup age. Remember that both dating types are ranges, carbon dating is not 100% accurate, and ancient DNA can be difficult to sequence. Haplogroup ages are refined as more branches are discovered and the tree grows.

The convergence of these different technologies in a way that allows us to view the past in the context of our ancestors is truly amazing.

All of our Crumley cousin’s ancient relatives are found in Ireland or Scotland with the exception of the one found in Wales. I think, between this information and the haplogroup formation dates, it’s safe to say that our Crumley ancestors have been in either Scotland or Ireland for the past 4600 years, at least. And someone took a side trip to Wales, probably settled and died there.

Of course, now I need to research what was happening in Ireland and Scotland 4600 years ago because I know my ancestors were involved.

Suggested Projects

I’m EXTREMELY pleased to see suggested projects for this haplogroup based on which projects haplogroup members have joined.

You can click on any of the panels to read more about the project. Remember that not everyone joins a project because of their Y DNA line. Many projects accept people who are autosomally related or descend from the family through the mitochondrial line, the direct mother’s line.

Still, seeing the Crumley surname project would be a great “hint” all by itself if I didn’t already have that information.

Scientific Details

The Scientific Details page actually has three tabs.

The first tab is Age Estimate.

The Age Estimate tab provides more information about the haplogroup age or TMRCA (Time to Most Recent Common Ancestor) calculations. For haplogroup I-FT272214, the most likely creation date, meaning when the SNP occurred, is about 1709, which just happens to align well with the birth of James Crumley about 1710.

However, anyplace in the dark blue band would fall within a 68% confidence interval (CI). That would put the most likely years that the haplogroup-defining SNP mutation took place between 1634 and 1773. At the lower end of the frequency spectrum, there’s a 99% likelihood that the common ancestor was born between 1451 and 1874. That means we’re 99% certain that the haplogroup defining SNP occurred between those dates. The broader the date range, the more certain we can be that the results fall into that range.

The next page, Variants, provides the “normal” or ancestral variant and the derived or mutated variant or SNP (Single Nucleotide Polymorphism) in the position that defines haplogroup I-FT272214.

The third tab displays FamilyTreeDNA‘s public Y DNA Tree with this haplogroup highlighted. On the tree, we can see this haplogroup, downstream haplogroups as well as upstream, along with their country flags.

Your Personal Page

If you have already taken a DNA test at FamilyTreeDNA, you can find the new Discover tool conveniently located under “Additional Tests and Tools.”

If you are a male and haven’t yet tested, then you’ll want to order a Y DNA test or upgrade to the Big Y for the most refined haplogroup possible.

Big Y tests and testers are why the Y DNA tree now has more than 50,000 branches and 460,000 variants. Testing fuels growth and growth fuels new tools and possibilities for genealogists.

What Do You Think?

Do you like these tools?

What have you learned? Have you shared this with your family members? What did they have to say? Maybe we can get Uncle Charley interested after all!
